I received mine last month, my fiance has an iphone 4 (not 4s). I've already loaded an AOKP ROM on it and have yet to have any issues. battery lasts a full day with the help of juice defender. Anyway, the girlfriend chooses to use my phone for playing around more than her phone lately. She's slowly trying to steal it
Great phone, alot of fun, and guarantees a good time. As far as getting the new HTC's, they may run faster and yada yada yada, but the GN still has my heart ^.^
PS: I'm on Sprint
