Can't connect to app store
I have not had any problem on my iPhone 5 and now suddenly, was in the middle of a purchase and it just stops and says can't connect. Now I can't do anything. It was seriously all of a sudden. Now I go to my laptop computer, bring up iTunes, try going to the store, nothing, it won't even come up there either. I don't understand this and can't figure out what to do.
iPhone 5, iOS 6.1.3
