Hello I am new to the forums and I have a Jailbroken Iphone 4 running 4.0.1 I jailbroke with Jailbreakme.com I have saved with tiny umbrella. I am not too sure what to use to update and re-jailbreak if I update to 4.1. I also am worried that I did not save with tinyumbrella the correct way. The save SHSH says "iPhone4 4.1" although installed firmware says "4.0.1" So I am very hesitant to upgrade to 4.1 without loosing my cydia app in particular "mywi" Any advice on what I should do. I searched the forums and could not find a fit. Please advise.
