You'll never believe this, but it looks like Cupertino might be getting ready to drop a bomb this summer -- a 3G bomb, in fact! The latest beta release of firmware 2.0 for the iPhone has apparently revealed a preference screen that allows users of the new model to disable the 3G radio and fall back to GPRS / EDGE because the faster service "decreases battery life." Gotta pay to play, as they say. The ability to disable 3G service in favor of improved standby performance is a pretty common one in modern phones, so we're not surprised to see it here -- just a little disappointed that Apple hasn't incorporated enough fairy dust to magically make the problem go away.
