I want to ask. My appstore show notification to update. But when i open the appstore, and go to update site, nothing comes up, even the 'purchased'. help me, im new in ios

I had the same problem. Updating to iOS 6.1 fixed it.

Sorry just noticed you're already on iOS 6.1. When I searched for an answer the suggestions were 1) reset by holding home & power button until the apple logo appears. 2) Sign out of iTunes in settings and then sign back in.

The suggested ways as what the butterflygirl2909 can also acceptable. But if it doesnt work, try using another language setting. Go to setting>international>language>select any language. Then open up your update appstore. Its work with me. If its doesnt work, worst come to worst is reset to factory setting.
