I restarted my iphone 4 shortly after i had it jailbroken. Now Cydia won't start?

I recently got my iphone jailbroken. And after a while of enjoying the wonders of the iphone, i decided to restart it. But any apps installed from installous or anything from Cydia and even Cydia itself won't start. Can some one help me?

Your Firmware Is Probably Too New.

You had a tethered jailbreak that means when battery dies or you restart then you must start up cydia again with it plugged into the computer. It should have given you the program (ibooty) that is what you use!
