"An unknown error has occurred" iphone 4 when downloading any app from app store
Every time I try to download any app (paid or free) from the appstore from my Iphone 4 I get this same error. Any help would be appreciated. I've tried updating my credit card info, as well as changing my apple ID password - neither had any effect. This is the first time I've tried to download an app after installing the latest iOS though. Anyone else having this same issue? or know of other things to try? Thanks in advance.
iPhone, iOS 5.1
