Iphone 4, jailbroken, ios 5.1. Problem like in the title, after updating cydia apps and respringing, iphone just wont load up. Restarting doesnt help. It also doesnt react to the top right button for turning off when loading. I can turn it off only by holding the 2 buttons together. I've read in a couple threads that with the help of itunes i will be able to "reset" the iphone, but i dont wanna lose all things i have on it. So my question is how can i get it to work without losing all the data? Can i somehow get it all on my pc from an iphone in that state? I couldn't write the whole thing in the title so i apologize. If more info needed go ahead and ask. Thanks for your attention.
