all of my apps are unable to update or download.
I've been trying to update and download a few apps but I keep getting a notification that it's unable to download. Ever single one is doing this! I've turned my phone on and off but it's not working. Do I have to get on WiFi inorder to figure out whats wrong? My other apps are working fine until I have an update for them.
iPhone 4S, iOS 5.1.1
