I have a 32GB iPhone 4 running 4.3.1 jailbroken with redsn0w 0.9.6rc9. Everything works fine up until I restore it using PKGBackup. Then the iPod app crashes immediately after opening. So I tried restarting, and up until I installed the YourTube 2 (ModMyi) and then my iPod app refused to open. I'm not sure the relation, but Google mobile doesn't open either. Please help!
