Hi guys so I have an iTouch 4G. So today Iwas using it and i noticed in my settings it said i was applicable for the upgrade. So i went to the settings menu. Click on check for update and IOS 6 popped up. I waited a couple minutes for it to do its thing and the second it finished my ipod restarted and I figured maybe it was a new feature or something. So slide to unlock and notice two thing. 1) my lockscreen pic is back to the default and 2) my password lock is turned off. So when I get to the homescreen I sign in and I notice 2 main ipod touch apps are gone. The first is the calculator (which is no biggy since I use a normal calculator) and the second was my app store!!! I freaked so I quickly googled my situation. I found multiple answers my first attempt was going into settings and restrictions and checking it off and then on but in the restrictions there was no app store option at all! At that point I freaked. I tried restoring it. Still nothing. The last thing I tried was searching it up in the main menu search screen and nothing pops up. I am so upset and I need it for presentations at school. So please somebody help!! Thanks in advanced. 2 thing u should know 1) My device is NOT jailbroken 2) my contacts are still on my device even after factory reset.
