I can't use any of my apps on my iphone 5?

I just recently bought an iphone 5 and when i go into the phone i can't go on any of the apps like app store an settings. What do i do?

I'm not sure if this will work, but try it anyways (it can't hurt anything) 1. Hold power button and home button for 10 seconds at the same time. It might work. Then, once it resets (it won't reset info) double click your home button, then (if there's any apps) hold down on an app in the little section that pops up. Then, press the little - sign on all the apps (there might not even be any) hope this helps.
