I've got a jailbroken 32gb ipad that i'm getting rid of and wanted to get it back to stock before it leaves. I was thinking about just syncing it to itunes and letting it do a system update on it. would that do the trick, or am I better off just doing a system restore? Which will erase everything best? I just want it to be a bone stock ipad with nothing on it that doesn't come from the factory. If this guy wants it jailbroken, then he can go figure that out for himself.
