Are you talking about jailbreaking or unlocking? You can jailbreak regardless of carrier.

Jailbreaking & Unlocking are two different processes. When you unlock an iPhone.. regardless of bootrom" you can use any GSM sim card. T-Mobile included.

if you are already jailbroken, open cydia and install ultrasnow.

Yes done that, but with baseband of 05.16.05 on newer bootrom you can not install that.Meaning it only unlolocks it for that carrier such as at&t when you jailbreak.Older bootroms with upgraded basebands on 06.15.00,or downgraded basebands on 05.13.04 you can install ultrasnow and it should unlock all carriers.I was having a problem with t-mobile and had to install MobileSubstrate 0.9.3995 to get it working with a older baseband.It was a pain,but I know it should have worked with ultrasnow..So there is a difference between newer and older bootroms what is the difference between unlocking and jailbreaking should be the same.So on the newer bootroms what do you use to unlock,you use ultrasnow for olderbootroms.

The bootrom doesn't really have anything to do with it. It's more or less the BB chip. If your phone was made before the 35th week of 2011 you are good to go to flash the baseband. after the 35th week though, apple used a different bb chip and it will not receive the iPad baseband. In a previous post you wrote "Having troubles with t-mobile after jailbreak old bootrom and 5.13.04" are you on 05.16.05 or 05.13.04? What are the 3rd 4th and 5th digits in your serial number? these numbers are the production date of your phone and will indicate if you can use the iPad baseband.
