iPhone 4S apps will not download, stuck on waiting
I have an iPhone 4s, latest iOS installed, and an iPad2 with the same iOS. When connected to my wifi at home, and in the office, my iPad will update existing, and download new apps from the appstore, but my iPhone will not. I can surf the web, and do emailing, so i am definitely online, but no apps, new or updating existing will get past the grey icon with Waiting underneath it. After 5/10 minutes of that, i get the message stating unable to connect to itunes, but itunes on my iPhone works fine, and the app store will load fine too.
I'm not interested in removing the grey icons, i want them to install, and i want to know why they're not installing. I know how to plug into iTunes on my Mac and do the updates/new installs, but that kinda defeats the object of having the iPhone with wifi.
Anyone have any idea what the cause could be, and how i can stop it from annoying me?
iPhone 4S, iOS 5.0.1
