No AT&T signal on unlocked 3GS; will TMo get one?

[worldwearyeyes]

I jail broke and unlocked my 3.1.2/5.11.07 3GS to sell on ebay. My AT&T sim gets the No Signal, which I've can happen. I used pwnage tool for Mac + ultrasnow.

My question is, will the buyer's Tmobile sim have the same problem or work okay? I don't want to send him a dud.

Cheeers...matt

anyone?

Your doing it wrong that's why instead of ultrasn0w it's supposed to be blacksn0w delete ultra and install blacksn0w
