3GS on 3.1.3 upgrading to 5.1 ultrasnow fixer
So i have an iPhone 3GS on 3.1.3 that is unlocked to t-mobile. I want to upgrade it to 5.1 and keep the unlock. i already know how to preserve the baseband using pwn tool. my question is since ultrasnow has yet to be updated someone has released ultrasnow fixer... i have only found a few success stories with it and i was wondering if anyone else has used it and successfully unlocked?

I'm also looking for confirmation that the ultrasn0w fixer works, as I'd like to upgrade to 5.1.

Stitching... Yes, meaning that it doesn't need to get a reply from apple servers.

That's the idea of it is going to that firmware and saving the blobs an then either stay there or downgrade back.
