All I did was change my apple ID password to a new one (just to be more secure). And now when I go to the app store on my iPhone 4S and try to download any app I get a grey empty app icon instead of the app logo with ''loading'' written on top of it and then a few seconds later it says Unable to download application. ''Glow draw could not be downloaded at this time. I restarted my iPhone and I still cant download apps. I'm really worried. I never knew changing your password could cause such nasty problems.
