Well, i did everything according to all the guides i've read in this forum. Problem: iPhone 3G - BB: 05.15.04 - IPSW 4.2.1 This is a old iPhone 3G i think, no matter what.. I tried to JB it, all went fine untill it rebooted, then it got stuck on the logo screen, so i went to TU, checked the settings etc... Still no JB, so, why cant i JB this iPhone 3G? I have done several JB's on iPhone 2G,3G,4G, and all went fine. All i want is to know why this phone cant get JB. I used redsnow, not latest, it was not compatible with my device, so it kept telling me, well, went back to an earlier version, checked Install cydia. And hoped for the best, stll hangs on the logo screen, nothing. Question, can i use IPSW 4.1 when my phone has 4.2.1 to jailbreak it or do i have to use same IPSW as the phone has ( 4.2.1 ) Tried everything, still not successfull, so i would like to ask some of the gurus in here what i can do about my iPhone 3G..
