The BlackBerry Onyx, also known as Driftwood 96xx, is rumored to be T-Mobile’s first 3G Blackberry. Physically it is somewhere between the bold (keyboard) and the Curve 8900. There is little official information about it, but so far, the rumored specifications are basically similar to a Curve 8900 + 3G, so we give this a good chance of being true. Some are wondering if it will support T-Mobile’s UMA. Nothing is certain, but we’re 99% positive that it will.
