Son of iPhone!

Dust off your sleeping bags and Therm-a-Rest and get in line, Apple’s 3G iPhone will reportedly arrive at market in just a few weeks.

“Someone very, very close to the 3G iPhone launch” tells Gizmodo that the device will debut as expected at Apple’s (AAPL) Worldwide Developers Conference 2008 on June 9 with immediate availability.

A plausible rumor, and one that jibes with other similar ones we’ve been hearing for some time now–specifically the one about AT&T (T) employees being asked not to schedule any vacation between June 15 and July 12 to ensure sufficient staffing for “an exciting summer promotional launch.”

Normally a consumer product announcement at WWDC would seem unlikely. That said, it would make sense for Apple to uncrate a next-gen iPhone at the event this year, given its recent software roadmap and SDK announcement. Wouldn’t it?
