+1 for the Seidio 3200mah. I think they might have a discount for some of the forum members, but don't quote me on that. Yes, it makes an already large phone into ZOMG HUGE!!!1one
but at least I never have to worry about that night where I don't make it home and my phone is dead before the next morning. I can pretty much go a whole weekend without a charge without super-excessive use.
