SN0WBREEZE version 4.1 to 5 PLEASE HELP!

[epiclycoolyasir]

I'm have an iphone 3gs version 4.1 JAILBROKEN and unlocked(network T-Mobile), I'm trying to upgrade it to ios 5 using sn0wbreeze; I want to leave it jailbroken AND keep it on T-Mobile. When selecting a mode it says all modes still preserve the baseband. I want to keep mine unlocked/jailbroken/t-mobile. So, do I do simple mode or baseband preservation mode? I'm watching a video it says baseband preservation won't leave it jailbroken. Please help.

use redsn0w instead. I'm not sure if sn0wbreeze has updated yet to be untethered. Just be sure you select preserve baseband. Tutorials on iclarified if you need them. Btw 5.0'is no Longer being signed by apple so you will need yo go 5.0.1
