I have an iPhone4 that is running iOS 4.1, and its jailbroken. Today, I installed a facebook app that crashed my phone and caused it to go into recovery mode. How to fix iPhone 4, iOS 4.1 in recovery mode without losing jailbreak? I obviously don’t want to restore through iTunes. I have heard of things like TinyUmbrella but need a guide specifically for me. I have no idea what SHSH are and where they are stored. I would be really glad if you can assist me on this. Please help.
