Iphone 3gs not working

[pokernrear]

I have a j/b 3gs on 4.0.2 shsh saved only for 4.0.2 I have cydia installed and have ran repo666.ultrasnow for the unlock. Turned off 3g and installed tmobile sim card but dont get any service. Any help would be great. Thanks in advance

Can you go into general settings and post your modem firmware version?

AFAIK, UltraSnow unlock doesn't work past 4.0.1 at this time.
