Hi there!
I'm kind of new to the forum, but I've followed your site for years, really great.

I'm having trouble with a recently bought iPhone 3GS, 4.1.2 on iPad baseband 06.15.00. The iPhone was locked to a european carrier (3), and I wanted it to my swedish carrier (Tele2). Using ultrasn0w 1.2 I thought everything worked fine, but I didn't get any reception! And no, it is not IMEI blocked, I didn't steal it, it works with other carriers like (3) and (Telenor). I've re-done the jailbreak using diffrent tools like greenp0ison and redsn0w, and I've reinstalled ultrasn0w multiple times, still, no luck. I have even contacted (Tele2) and asked them to "reboot" my SIM but still no reception.

So, am I screwed or do you have any suggestions? I'm stuck so any help at all is greatly appreciated!
