I think that you can use snowbreeze to upgrade your baseband to 06.15.00 the iPad baseband.

You can use Redsn0w to upgrade to iPad baseband, then unlock it with Ultrasn0w from Cydia. In addition, never, ever, delete a Cydia repo again.
Note that before you can re-jailbreak, you have to perform a fresh restore via iTunes (non-custom firmware), then jailbreak with Redsn0w (with the Install iPad Baseband option ticked). Good luck.

you can backup normally.. if you have JB that iphone before without having this problem do the same thing but make sure u've installed iPad baseband from the latest redsn0w version. then after installing cydia install ultrasn0w in order to unlock your sim and get service. hope that will help
