I had to change my email address and password via the ITunes store from my PC, but now I cannot download apps via the phones app store icon. It still has the original email address but everhing has changed and the original password or the new password doesnt work. Any suggestions?
In iPhone Settings > Store > Apple ID > sign out and sign in with your new Apple ID.
