Lost my apps and waiting for cell service

So I did the pwnagetool and it worked and updated me to 3.0, but I lost all of the cydia apps and my phone says is is waiting for activation.
Did I do something wrong, am I missing a step. Should I redo it?
I can't even use my phone to make calls.

I have a 3G, was jailbroken, and the latest firmware I think of 2.2.5. Don't know if it helps, but I jailbroke this originally on my PC and just did this jailbreak on a friends mac.

Please help.
Thanks in advance.
