Once I use the blackra1n to jail break my 3gs 3.1 OTB can I proceed to unlock it with ultrasn0w? Thanks.

blackra1n works like charm. sweet! hope there'll be an unlock soon!

@humblehyper: nope!

Afraid not. There is no unlock currently available for the latest baseband.

sweet so we dont need to backup our phones or anything? Just hit "make it ra1n"?
i have a 32GB 3GS 3.1 OTB factory unlocked.

Worked great here!

NB: Blackra1n does work on the ipt3, but it is a *tethered* JB.

I haz success jailbreaking 2 iPhones with blackra1n, one is a 3G, the other a 3GS, both on FW3.1.2 and with official ATTUsa SIM

I cannot use Tmobile because there is NO UNLOCK for FW 3.1.x

Ultrasn0w does NOT work on FW3.1.x

blackra1n does NOT work if you do not have a legit authorized SIM

currently the best thing about the jailbreak is I have discovered I can play Pandora in the background, thanks to Cydia and the Music Controls application.. it ROCKS!

alright went ahead and just jailbroke my factory unlocked 3GS 3.1 OTB. thanks a lot geohot.

does exist a chance that this jailbreak will avoid me to unlock the IPhone in the future?
