So let's say I get fed up with the jailbreak scene, and decide I want to return to 4.1 stock. Is it as simple as connecting my iPhone to iTunes, clicking Restore, and sitting back? I've read of some people getting "Cannot Connect To Update Server" error messages and being stuck in DFU mode with 3014 errors, etc. Has anyone tried to restore back to stock 4.1 from Limera1n 4.1 jailbroken state on an iPhone 4? Cheers.
