So I was on 2.2.1 before and I decided to restore to 3.0. Which I did and noticed alot of battery problems so I restored it to 3.0 a couple times. I know how to restore and I know how to jailbreak/unlock a phone, iv done many. While I was on 3.0 I saw I was having problems connecting to a wifi spot. Then when i restarted it finally went grey on me and couldnt even click on it. So i decided to go back to 2.2.1 and see if it was a 3.0 issue. So i downgraded to 2.2.1 and unlocked it with ultrasn0w and everything works fine but the wifi is still greyed. Can any 1 tell me how i can fix this? Thanks alot
