I just recently sent my iphone 4 into Apple to have it exchanged with a referb unit. What happens to me now? Providing the phone has never been jailbreaked before and doesn't have any SHSH blobs saved with Cydia....where does that leave me? Will I be able to set up as a new phone on 4.2.1 and jailbreak (Windows) without have a tethered jailbreak? Is it possible apple will send me a referb with 4.1 on it? Or will it always be the freshest and newest firmware? If they did send me a iP4 with 4.1 on it, I may be able to jailbreak that with greenpoision and save my blobs. Please advise as much info as you can... THanks to everyone in advance!
