Im stuck with a bit of a problem, I recently download the latest firmware v1.2 / 2.0 beta 4 and install it on the phone, and then finally realize that I cannot find anything to unlock beta4. I tried to downgrade back v1.1.4 but I got an 1604 error in iTunes and now the best I can do is reinstall v1.2 and get stuck with the purple screen...
My question is:
1. Is there anyone out there that successfully unlock/jailbreak v1.2 (SDK 2.0) beta 4, and if yes with which tool (by the way Im on MACOS).
2. If there's no such tools, how can I downgrade back to 1.1.4, and get rid of the 1604 error in this specific case, I tried everything that they say on this address:
http://docs.info.apple.com/article.html?artnum=307007 without any success.
Thanks in advance!
Cheers!
