AT&T, Verizon,T-Mobile and Sprint Will All Carry BlackBerry 10 Phones

When Research In Motion launches its new line of BlackBerry 10 handsets later this month, it will do so with the support of all four major U.S. wireless carriers. AT&T, Verizon, T-Mobile USA and Sprint have all confirmed plans to offer BlackBerry 10 devices on their networks. Hardly surprising, considering RIM has longstanding relationships with all four. That said, their support is obviously crucial for RIM’s effort to recover from an ugly decline that has left it with just over 5 percent of the global smartphone market.
