Does anyone have any idea why my wifes 3G phone has stopped being able to make calls? Everything works on the phone EXCEPT the ability to make calls. Yes, the bill is paid. ;-)

My phone is exactly like hers. I'm using jailbroken version 3.1.2. I hate to say it, but I forgot how I jailbroke hers. I used blackra1n on mine, and thought I did on hers, but the her icon is gone. Maybe she deleted it. I've been so busy the last few months I haven't done much with my phone except just use it!

Anyway, thanks in advance for the help.
