Iphone 3gs, 8gb, T-Mobile, jailbroke with pwnage, unlocked with ultrasn0w on baseband 06.15.00.

I did this the first day pwnage and ultrasn0w came out with the 06.15 baseband unlock. I had no issues until yesterday my battery started draining like crazy. I notice the date usage keeps going up, so I installed SAM and SAMprefs and activated the phone the way the directions say. In SAM ActivationState: is WildcardActivated, SAMState: Loaded OK.

Anyone no if this is all correct and why the battery is draining very fast? Again, I did not have this issue when I first unlocked last week. It started on Monday and have really not done anything else to the phone.
