Hi all. I have a iPhone 3GS which is locked for about 4 or 5 months now and want to ask if the solution is out to unlock it. It was upgraded by stupid mistake to firmware 3.1.3 or whatever and ever since I can't use any feature at all. It just displays the damn USB icon

Please guide. thnk you.

There is a current solution by msft.guy (thanks!), but it's not for the feint of heart. Read about it here:

Mostly iPhone hacking: OLD BOOTROM + Spirit => 4.0 JB

Note that you *MUST* have an OLD BOOTROM, or this cannot work for you. If you've got a new bootrom or do not have a 3.1.2 SHSH on file, you'll have to wait until the new tools are released.
