i got an iphone off ebay, locked to orange, new but already activated. Model MC131B Baseband 05.11.07 Heres the problem, jailbroke with blackra1n, no problem, installed apps, wifi worked, everything sweet. Used sn0w to unlock and put simcard in, it displayed O2-UK but had no bars so calls couldnt be made, did some googling around and it suggested i reset network settings, it "seemed" to work, i got a bar, but then it went to "No Service" after 10secs, and i had nothing but probs since. Spent a long long time trying different stuff and still getting no joy, after 1 restart blackra1n didnt boot the phone back up so kept trying diff boot methods like holding both buttons, releasing diff times etc, after some tryin 10x it booted up, so i put the T-Mobile sim in (which is the 1 needed to be used in the phone) and again joy, bars and T-Mobile written there, but it was short lived, no ability to make calls etc, tried the reset network thing again and couldnt get blackra1n to boot again, tried it 20 or 30x. So (sorry to ramble) to my point about redsn0w, downloaded latest version 0.9.4, loaded the right ipsw and let it run its course, saw the running pineapple, it froze at 50%, restarted it (tutorials said just try again cos it happens regularly), after 3 or 4 attempts it worked, but after the rebooting message it simply rebooted back to showing me the usb plug pointing at the itunes logo Anyway i tried running redsn0w a few more times with the same result every time. I tried blackra1n again with no joy. Can anyone help? ps. the shsh for 3.1.2 is not stored on cydia so cant restore with PwnageTool, i did get cydia to do the shsh for 3.1.3 if this helps, although i really wanna stay with 312 if i can for now, cos god knows when geohot will release the new hack, it could be months away!
