I just recently had to purchase a new Iphone 4 and jailbroke it just like my other using Limera1n, something happened in Itunes and it would not detect my phone so I had to restore. By doing this it installed 4.2.1, do I have any options to get my jailbreak back? I saved my SHSH on 4.1 on my other device, but not this one. Is there a way to use tiny umbrella to restore this one to the old firmware? Thanks for the help!
