I bought it used, had it flashed to Metro PCS and had internet and picture mail unlocked. I'm new to Smartphones, so I really have no idea. Just looking for a little guidance. The guy that flashed it and unlocked told me that if I do a hard reset he'll have to redo everything he did to unlock the internet and data, so I'm afraid to hard reset it....LOL. Any suggestions on were/how to check whats draining the battery? Thanks.
