How to upgrade and unlock iPhone 3gs?
I have an AT&T 3gs jail broken to accept my T-Mobile sim. It is running 4.1(8B117) on 06.15.00 firmware. Because the version it's running I can't download anything and Cydia as well as my network often don't work and I get poor reception in most places. What is the procedure to upgrade to the latest version (or one that is close to it) while still being able to use the T-Mobile Network?

You can update your 3gs all the way to iOS6, I believe you can update with iTunes, and then unlock with ultrasn0w.
I recommend you put Apple's firmware back on it and instead of using a jailbreak for your unlock you just get a factory unlock. If you get a factory unlock they are permanent and updates don't affect them because the unlock is on Apple's servers rather than on the phone itself. Lots of places do factory unlocking for a good price (i.e iphoneunlockedcheap.com)

- I recently bought an iPhone 3gs and I can't get it to unlock with iTunes? I put my T-Mobile sim card in the phone (the phone is unlocked for tmobile) and i connect it to iTunes and it says "The SIM card in this iPhone does not appear to be supported" why is this happening? Should I just give up on it and take it to the apple or T-Mobile store?
