Hello and thanks for reading. I am appreciative for any help. 1st gen iphone, bought it when 1.1.1 came out, i am pretty sure, if not it was 1.0.2. I am on a Macintosh. Was running 1.1.1 hacked to use on T-Mobile. So here is the deal.When 2.0 came out, I read around for a bit, got a bad jailbreak/upgrade tutorial and upgraded to 2.0 before I cracked the phone. I knew this was not right but the tutorial said to do it. It didn't work of course. So I downgraded to 1.1.4 but it would not recognize my T-Mobile SIM. I think this is what they call "bricked?" So I tried to upgrade again using the PwnageTool again. Still wouldn't recogize my SIM so I downgraded to 1.1.4. I have read around a lot and there is not a lot of information on how to go to 1.1.4 to 1.1.1 successfully using a Mac. OR how do I completely start again or am I screwed? I have spent like 14 or so hours on this, I know a decent amount now, but I really don't want to go any further unless I can confirm the path and I can't find anything about this online, oddly enough. Anyone can help with either stage of downgrade to 1.1.1, revirginize, or how to get my sim working? You will be my hero for the month, no joke.
