something is screwed up and my battery is not right, like 20% remaining on 1 hr usage and 6 hour standby.

what is my best option for update/jailbreak? i'm on AT&T and want to be able to unlock when i sell the phone later this summer. is snowbreeze and custom 3.1.3 ipsw the best way?

thanks for your help.
