Hi, I have a relatively new iPhone 3GS running 3.1.3 I need to restore to 3.1.3. My old 3GS was on file with Saurik's SHSH server, however it was replaced by Apple AFTER he clsoed registration for his server, so this one is not. I was hoping to use TinyUmbrella to manually accomplish the same thing Saurik had done.... but the new version of TU does not seem to "work" on my 3GS. Is it only designed for iOS4 now? Does anyone have any material I can read on accomplishing what I want to... if it's even still possible? Thanks for any help.
