So, here's my story I have a 16 GB 3GS, which came with firmmare 3.1 on it when bought it (less than a month ago.) I tried to jailbreak on 3.1 using PwnageTool 3.1.3, and ran into some problems when I created the custom firmware, it wouldn't install via itunes. So when PwnageTool 3.1.4 came out, I went ahead and downloaded OS 3.1.2, then created custom firmware, and installed it. Worked like a charm... except there was no connection to AT&T. I tried resetting the network inside the iphone, then I tried reinstalling the custom firmware... neither worked. I ended up having to reinstall the standard 3.1.2 software, and when apple asked me to update my carrier settings, I said yes. Luckily, I still have an iphone that works. However, I would much prefer to have a jailbroken iPhone that works. Does anyone have any idea how I could go about doing this? Great buckets of thanks in advance if you can help. -- Nate Avery PS I hope this isn't a repost... I wasn't able to find any answers in any of the previous threads.
