T-Mobile's G2 will have the new Snapdragon inside set at 800MHz, the battery says thanks2
When you clock it at the minimum, you get even more juice out of the battery, and graphics performance will be up to four times better thanks to the new Adreno 205 GPU in this chipset. We can't wait to see what talk and standby times will be on the G2, probably vastly improved, similar to the other 45nm offerings on the market like Samsung's Hummingbird, and the OMAP3 in the two latest Motorola DROIDs. The G2 is rumored to cost $199 with contract, and $499 without.
