okay here is my story, i was on 4.2.1 jailbroken and such. i reformat my macbook. so now my new macbook pro only has 4.2.1 backup. so the problem is... i downgraded back to 4.1 and i want to use my backup but cannot... since the only backup i have is 4.2.1. is there anyway to go around this? or do i have to go bak to 4.2.1 >_>;
