Do I need Ultrasn0w
Ive been jailbreaking my 3GS for ages now but theres one thing im confused about.
I brought my 3GS in the UK on O2 network. I paid O2 to get it officially unlocked so I could use a tmobile sim (as at the time i updated to 3.1.3 and there was no jailbreak tool).
I then JB with spirit when i realised i had my SHSH backed up. Once i dont this my sim would not work so I had to use ultrasn0w to unlock it.
I want to know if im able to use my tmobile sum without having to use ultrasn0w as it stops my push notifications working and a few other things??

do you have access to another network sim, vodafone maybe?
i bought mine on o2 before any other networks sold them, i too had it JB on 3.1.2 then had o2 unlock it for £20 on a payg sim, it worked fine, then i JB on 3.1.3 with spirit and i was able to use my voda sim without ultrasn0w, i'm thinking it might be t-mobile as they do seem to cause problems on the iPhone

This is my understanding of how it works.
Carrier unlock = software just like ultrasnow. Restore the device or wipe it, wipes out that software unlock
Official unlock (bought from apple unlocked) and the locking software is not even present so restores/wipes do not remove this unlock.
Correct me if im wrong?
