I need some help. I currently have an iPhone 4 on 4.1, I want to upgrade to 4.2.1 and then use GreenPoi0sn to jailbreak it. Everytime I go to upgrade or restore to 4.2.1 on itunes I get the 3194 error. Is there a version of tiny umbrella out yet to help me get my 4.1 upgraded to 4.2.1? Thanks for any help
