Well I managed to mess up, sort of, my iPhone. I just got it today, and it's on 4.0.1 I jailbroke it, with jailbreakme.com. I noticed i couldnt use so many things from cydia, so i decided to downgrade... Well, my shsh blob thing is still pending on Cydia. I have manged to use the umbrella program to save it to my pc. So i can't downgrade to 3.1.3, and then i decided to put a theme on my dialer, and i used ssh to backup the entire mobilephone.app folder to my pc, i add the theme on there, it didn't work, so i deleted the entire folder, and copied it back on..and i noticed on filzilla, it had some red entries on the message log. When i went back to use the dialer app, it crashed..i didnt even get to get on it. So, can anyone help me? If i dont have a 3.1.3 shsh blob saved, will i ever be able to get back to 3.1.3?. (or until compatibility issues are all fixed for iOS 4) -Edit: I also am not able to restore, at all. I put my phone in dfu, and tried again, but it gave me error 21, and again i tired it, and error 1602.
