Default [Q] Locked Desire, can't send/receive texts or calls but can connect to 3G

Hey,

I got an HTC Desire that was blocked, and decided to try unlocking it. I tried everything: the unlockr program (v0.9.4 and 0.9.5), it says "Done!" and and then when I try putting my Virgin sim card in it, I have 3-4 bars of signal, but can't send/receive texts or make/receive calls. But if I activate the 3G, I can go on the internet. I checked the service center number, it's the correct one. I checked everything I could, I flashed the radio to another one, S-OFFed it, ... Don't know what else I could do. Looks like it's blocked to everything.
Here's what's written on my HBOOT:

-Revolutionary-
BRAVO PVT1 SHIP S-OFF
HBOOT-6.93.1002
MICROP-031d
TOUCH PANEL-SYNT0101
RADIO-5.11.05.27

Any help to unlock it would be appreciated.

Thanks!
