My friend let me take her iPod home to update it because she couldn't get many apps without it. When i plug it in and go to iTunes i click check for update it says version 4.2.1 or something i click update. It then says it couldn't connect to Apple, but i know i am connected to the internet because i can get on facebook, and MacRumors and any other website. She is counting on me and i would like to fulfill her request.
