Test Report: CDMA 800 & 1900, CDMA EV-DO Release A 800 & 1900, Bluetooth, WLAN
SAR Report: Model SNN5865A - 1500 mAH Battery
So, a Verizon phone with a 1500mAh battery! Whatever this thing is it's HUGE. The Sprint EVO is the only other thing I know of that does 1500mAH so maybe this device is a 4.3"'er.
