Heh ho after waiting god knows how many months before Jailbreaking the bug finally bit me yesterday Read all the instructions carefully. (And thanks to spinstorm for the great guide. http://forums.macrumors.com/showthread.php?t=550964) I used pwnagetool and all went well. "Easy as pie", I thought. Got my settings all nice and restored. Excellent. Except well, except there was no sign of O2. Jailbreaking had turned my iPhone into an iPod Touch. I could go wild and install and customise to my heart's content unless I wanted to make or receive a simple phone call. Great. Took the Sim card out And the iPhone recognised that a sim card had been removed so I replaced it nothing. Plugged it into another Mac. No sign of any O2 network connection. Still not giving up I rebooted again, cursed, prayed, hopped around mad stood outside in the street waving the phone in the vain hope of catching a signal nothing helped. In the end I was forced to go back and do a wipe and restore. And here I am again back at square one: plain old vanilla iPhone. Nothing special, but at least I can make a damn phone call! I would dearly like to give Jailbreaking a try again but do I have another 4 hours to waste? Any hint as to what I did wrong although, trust me when I say I followed the instructions to the last letter.
