I have completely restored the phone to original. When I received it, the phone had a custom ROM and was roaming. I restored using ODIN the atlas_v2.2.2.pit and CI500_VZW_EH03_GB_CM.tar.md5.

Phone currently reads the following;
PRL: 52612
ERI: 00005
Network: Roaming
HArdware: I500.04
Model: SCH-I500
Firmware: 2.3.5
Baseband: S:i500.04 V.EH03
Kernel: 2.6.37.7
Build: SCH-I500.EH03

Any assistance would be greatly appreciated. Thank you!
