If you have a iPhone your son put a pass code lock on and he for got it is there a way to reset it ATT 3G
You'll have to sync it to the computer you did when he first got it. It will restart it, and the pass lock will be gone. It might delete all the stuff on his phone though if he hasn't synced it in a while.
Take it to the AT&T store they can really set it my son de it to my phone and they get it done
Have to call ur network provider
Plug it into your computer and right click on the iPhone under devices and click back up then left click on it and push restore and let the computer do it's thing.
