Ever since i downloaded ios7 my iTunes store app wont open. It does for about a second then glitches out. Ive already tried restarting the phone and closing the app

your gonna have to wait for a software update (or do a total reset of the phone, which you would only do if you knew that would 100% work, which it might not) sorry. i found a ton of glitches that cant be fixed without some sort of update. try this glitch: in lockscreen call any number for the emergency call number and hit call multiple times until apple logo appears. it will appear to have resprung but it will call the number you dialed. another lockscreen bypass.
