iPhone 3GS IOS 5.0.1 with 06.15.00 BB

[iPhoned00d]

Hello everyone! I have an iPhone 3GS Jailbroken & Unlocked with Ultrasn0w from Cydia on the 06.15.00 BB with IOS 5.0.1. For some reason, everytime I put my T-Mobile SIM Card, it will say, "searching" then to "no service". I've tried uninstalling Ultrasn0w and reinstalling and still nothing. Can anyone help me here?

Same problem here

I've got a 3GS with the old boot rom, 5.0.1 installed and iPad baseband 6.15.00 installed. I've reinstalled the iPad baseband several times using Redsn0w 0.9.9b8, also uninstalled and re-installed ultrasn0w several times, with no success of getting a T-Mobile signal.

Same problem

I have the same problem I accidently upgrade my iphone to 5.0.1 with baseband 0.5 16.05 then I swith to ipad baseband in order to be able to run ultrasnow 1.2.5 with cydia but every time i run it, it says "could not active the cellular network data" and then when i put the SIM card in (virgin) it searches and says no service.

I tried to reflash to restore, to reinstall ultrasnow, to switch on/off airplane mode I went to carrier i switched off automatic.

Nothing worked for me
Somebody have a idea for me
thank you
