First time iPhone user, got the 4s and had no problem the first week. But the past 2 days everytime I go to the app store to do an update or try to install an app it says "unknown connection error". I've double checked the password and it all works fine on itune and also in the app store on my ipad. It is a big pain to have to connect to the computer and sync to make updates. Any ideas for fixing this would be GREATLY appreciated!!
