Not on another page... It's vanished. Is there a way to re- download it? It appeared after I upgraded to 4.2.1. But now that I did the restore it's gone.
Sorry haven't answered for awhile... I'm not jailbroken. I give up on Gamecenter. I personally don't use it, but my 7 year old is kinda pissed off because it disappeared... Oh well, too bad for her. Maybe I'll be able to use my phone more now!
