Cellular Service Missing after Jailbreak

[kdesign7]

Could anyone tell me while my Cellular Service is now missing, after I backed up my SHSH and then used Spirit?! In the top left hand corner, I have NO SERIVCE, and when I go to Settings, then under CARRIER it just lists AUTOMATIC and then it says SEARCHING...

any help would be lovely.

Yeah mine was temperamental yesterday. I forced a restart by pressing home and power button down until machine hard reboots. Working ok since.
