Awhile back I looked at a tgread like this, to solve yiur problem, just plug your iPhone in your computer and it should come out unlocked after doing it... Google "forget 4 digit code iphone"
you should of asked Santa for a brain in the first place sooooo........your screwed big time when you get to third grade
too be fair, you didnt really add anything but rudeness and immaturity to the thread. Sooo, you would be the wrong one.
As far as I know, a restore is the only solution. Hopefully you have a recent backup (that isn't corrupt.)
