Complaints about dropped voice calls, or calls that can’t be initiated, on AT&T’s service, especially on iPhones, have been legion. Meanwhile, Verizon has enjoyed a general reputation for reliable voice service. So, many frustrated AT&T iPhone users and those scared off by reports of dropped calls, or simply loyal to Verizon, have been eagerly anticipating this move. To these people, I’m here to say: Yes, there are some major benefits to having your iPhone on Verizon, but, as with all good things, there are also trade-offs.

I’ve been testing a Verizon iPhone 4 and comparing it to an AT&T iPhone 4, which has been out since last summer. The phones themselves are essentially identical, except for the fact that they have different radios inside to accommodate the two carriers’ differing network technologies. They aren’t interchangeable.

On the big question, I can say that, at least in the areas where I was using it, the Verizon model did much, much better with voice calls. In numerous tries over nine days, I had only three dropped calls on the Verizon unit, and those were all to one person who was using an AT&T iPhone in an especially bad area for AT&T: San Francisco. With the nearly identical AT&T model, I often get that many dropped calls in one day.

Calls on the Verizon unit were mostly crisp and clear, including speakerphone calls and those made over my car’s Bluetooth connection. On my first full day of testing, I did have several Verizon calls that dropped out for a few seconds, before recovering. Apple attributed this to a very minor glitch I’d encountered in my initial setup of the phone and urged me to reboot it. I did and suffered no more momentary dropouts.

The Verizon model also introduces a feature that some iPhone power users have been craving but that AT&T hasn’t allowed in the past: the ability to use the phone, for an extra monthly fee, as a Wi-Fi hot spot for Internet connectivity to multiple laptops or other devices. In my tests, this worked fine with Windows and Macintosh laptops, and an iPad. Wednesday afternoon, AT&T countered by announcing a similar Wi-Fi hot spot plan for the iPhone at an unspecified future date.

For an extra fee, Verizon iPhone users can use the phone as a Wi-Fi hot spot. AT&T has rushed to counter this feature with one of its own.

Also, Verizon is, for an unspecified but limited time, offering an unlimited $30 a month data plan for the iPhone. That is something AT&T once offered new customers, but has since replaced with capped plans offering fixed amounts of data at $15 or $25 a month. (Existing AT&T customers have been allowed to keep their $30 unlimited plans.)

What about the trade-offs? Chief among them is data speed. I performed scores of speed tests on the two phones, which I used primarily in Washington, and its Maryland and Virginia suburbs, and for part of one day at Chicago’s O’Hare Airport. In these many tests, despite a few Verizon victories here and there, AT&T’s network averaged 46% faster at download speeds and 24% faster at upload speeds. This speed difference was noticeable while doing tasks like downloading large numbers of emails, or waiting for complicated Web pages to load. AT&T’s speeds varied more while Verizon’s were more consistent, but overall, AT&T was more satisfying at cellular data.

Also, because Verizon’s iPhone—like most other Verizon phones—doesn’t work on the world-wide GSM mobile-phone standard, you can’t use it in most countries outside the U.S. AT&T’s iPhone does work on this standard, and can be used widely abroad, albeit at very high roaming rates. In the midst of my testing, I had to travel to Hong Kong, one of the few countries where the Verizon iPhone functions. But even there, it only worked for voice, not data, at least in the areas where I was working. The AT&T model handled both voice and data everywhere I tried it there.

Finally, the Verizon model can’t fetch Internet data at the same time it is making a voice call, something the AT&T model can do. In fact, if you try to, say, call up a Web page while on a voice call with the Verizon model, you get an error message warning the two things can’t be done simultaneously. While this distinction is a weapon in the war of words between the carriers, I doubt it’s a big deal for most average users. My guess is that the most common things you’d want to check while talking would be your calendar, contacts and notes. And, in my tests, it was possible to check all those things on the Verizon model during calls, even though I have them set up to sync via the Internet.

I did have some issues with the Verizon model. In the D.C. area, long a coverage stronghold for Verizon, it kept switching briefly from 3G mode to slower 2G mode. This didn’t affect voice quality, and didn’t last long, but it slowed data downloads drastically for short periods. Also, on my first day of testing—after the setup glitch but before I rebooted—the Verizon phone showed poor battery life, and had trouble connecting to my car’s Bluetooth setup. After that, these problems disappeared. Bluetooth worked fine and I was able to make it through a day with the battery on both phones.

Apple lists the specs on the two models as identical. They both start at $199, both have the same battery-life rating, both run the same operating software. In my tests, I was easily able to transfer all my apps, music, photos, settings, music and videos from the AT&T iPhone to the Verizon model, using iTunes, and I didn’t run into any apps or media that failed to work as expected.

Prices for voice and data plans are a bit different. The least you can pay monthly for an iPhone on Verizon is $75, which includes 450 voice minutes, 250 text messages and unlimited data. On AT&T, you can pay just $65, but your data is limited to a paltry 200 megabytes, though you get 1,000 text messages in this scenario.

The Verizon wireless hot-spot plan costs $20 a month for 2 gigabytes of data, but gets expensive if you run over: $20 for each extra gigabyte.

One big question about the Verizon iPhone that neither company is answering is whether it will be updated to a new iPhone 5 model when the AT&T model is updated. Such updates typically have occurred in June or July, which could make people who buy a Verizon iPhone now resentful that their new phone was bested so soon. Of course, Verizon customers who wait might be resentful if their version of the iPhone isn’t upgraded at the same time as AT&T’s.

Officials at both Apple and Verizon will only say they don’t intend to make Verizon customers unhappy, but that could mean anything.

Bottom line: In my tests, the new Verizon version of the iPhone did much better at voice calling than the AT&T version, and offers some attractive benefits, like unlimited data and a wireless hot-spot capability. But if you really care about data speed, or travel overseas, and AT&T service is tolerable in your area, you may want to stick with AT&T.

Terms of the all-cash deal were not disclosed.

AdInfuse is one of scores of small companies that have sprung up in recent years on the assumption that advertisers would be eager to reach consumers on their mobile phones. They have entered the fray with a variety of business models, from building Web sites designed specifically to be visited via mobile devices to creating technologies that deliver ads in text messages. Since January 2006, about 80 such companies have raised more than $1.2 billion in venture funding, according to media and marketing investment bank Petsky Prunier.

It allows users to quickly notify neighbors when, say, a local river is about to flood or a rash of burglaries have occurred on the block. In fact, the inspiration for the service came nearly four years ago during Hurricane Katrina, when a Microsoft general manager named Tammy Savage began examining ways to help communities ready themselves for disasters.

But will Vine actually work in the most severe catastrophes, when there’s no power to run PCs and recharge cellphones?

Vine currently operates through three forms of communications: emails, cellphone text messages and alerts that are sent and received through Vine’s client software. Eventually, Microsoft plans to add the ability to receive alerts through landline telephones.

She compared the techie conversations that were going on around her with people speaking in a different language. And she isn’t alone.

Though it isn’t always obvious, the technology industry sees senior citizens as a target demographic — especially where cellphones are concerned. Mobile phones could act as valuable lifelines in health-related situations and, at the very least, provide an easier way for relatives to keep in touch. Major cellphone carriers offer models that they say are easier for seniors to use thanks to big buttons and large screen fonts. But some companies go a step further. GreatCall Inc., for example, designed its Jitterbug cellphone specifically to appeal to non-techies, including — but not limited to — senior citizens. It shirks phone extras like Internet access for simplicity and includes a concierge service that does things like remotely adding numbers to the phone so users don’t have to do it.

This week, I took a look at a cellphone that was designed specifically for senior citizens: the ClarityLife C900. It’s the first cellphone from Clarity (clarityproducts.com), a division of Plantronics Inc. (PLT) that specializes in telephony (landlines and other products) for people with hearing loss. The cellphone incorporates features that are useful for someone who may be hard of hearing or using a hearing aid.

The C900 is a bulky slider phone with a top half that slides up, revealing a number keypad below; number keys each measure a half-inch square. This might be a deterrent for seniors who want their phone to look hip or slip easily into a pocket. But Clarity says the phone’s deliberately large size makes it easier to hold and use, and accommodates a roomy 2.5-inch screen.

I found the C900 relatively easy to navigate with sensible on-screen commands, though there were a few times when I couldn’t back out of a screen and had to close the slider to start over. Friends’ voices sounded loud and full when heard through this cellphone, though it lacks a speakerphone, which my grandparents could use for calling relatives and singing “Happy Birthday” together.

The $270 ClarityLife C900 has oversized buttons and a red emergency button on the back that, when pressed, calls five contacts.

The C900 costs $270 — a steep price because it’s “unlocked,” or not tied to any one carrier, but according to Clarity’s research, senior citizens don’t like to get into long-term contracts like two-year deals. This unlocked model will work on any GSM network, like T-Mobile or AT&T (T), but buyers must take the phone to a carrier’s store to get it set up and working. The phone also could be added as one of the lines in an existing family plan.

People who would rather save money than avoid contracts can get the ClarityLife for $185 tied into a one-year service deal with T-Mobile. These monthly service prices range from $19 pay-as-you-go (20 cents a minute) to $99 for unlimited calling.

The hearing-related features on this cellphone include a 20-decibel speaker and a way to notify people of incoming calls using simultaneous ringing, vibrating and a flashing green light. All the buttons on the device make loud noises, including those that control volume. The C900 is also hearing-aid-compliant, meaning it won’t cause static interference when held up to an ear with a hearing aid.

The C900 has a large, red button on its back side that, when enabled and pressed, automatically calls and/or sends text messages to a list of five emergency contacts until it reaches someone. These contacts are notified via an automatic dialing system and must press “0″ when they answer to accept the emergency call so the system knows that a real person picked up, instead of a voicemail or answering machine. Five postcards with instructions come with this phone, and can be mailed to emergency contacts so they know what to do if they receive an emergency call from the C900 phone. Users could potentially add “911″ to their list of emergency callers.

Most people will likely use the C900 in its closed slider position, revealing just four buttons at a time. These oversized buttons can scroll through contacts, call friends and end calls. A feature called “Top 10″ lets users add their 10 most frequently called numbers in the order they prefer, which is a refreshing change from the alphabetical listing that most phones use.

The C900 accepts and sends SMS, or text messages, and comes loaded with nine canned text messages including the ominous, “I don’t have much time.” An extremely loud chime sounds when messages are received or sent.

Other helpful features include a hard button on the phone’s top edge that opens an alarm-clock function, and a button for an ultra-bright, built-in flashlight. This could come in handy, though it must be held down to stay on.

Clarity says that the C900′s battery life lasts for three hours of talk time or 150 hours in standby, and that it takes one hour to fully charge after the phone’s first-time-use four-hour charge. I left my fully charged C900 powered off for a couple weeks and it still had a full charge when I turned it back on again. This could be really helpful for people who forget to charge their phone, but want to grab it to take along on a trip.

A phonebook entry titled “Customer Care” comes preprogrammed on all ClarityLife C900s. This number is answered by Clarity’s customer-service team, people who are trained to consider a caller’s specific issues, such as hearing or memory loss. The representatives speak slowly, avoid tech jargon, and can use an amplifier to make their voices louder and easier to hear.

The ClarityLife C900 is expensive, but this phone’s hearing-targeted features will be appreciated by many seniors, as will its oversized buttons and easy-to-hold size and shape.

4INFO works with media companies, including Yahoo (YHOO), IAC/InterActiveCorp. (IACZ) and Gannett (GCI) to provide weather updates, sports scores and other information via text messages that contain small ads. The Silicon Valley start-up sends more text messages in the U.S., by volume, than any other provider, according to Nielsen. 4INFO says it delivers more than 80 million user-requested text messages per month and that its network includes 16 million users.
