Note: To use unsigned programs, you need the tetherdboot tool from http://cloud.github.com/downloads/msftguy/syringe/tetheredboot.zip . Unzip the ipsw, and put the iBSS.k48ap.RELEASE.dfu and kernelcache.release.k48 someplace, like your home directory. Put the iPad in DFU mode, open the terminal and do tetheredboot iBSS.k48ap. RELEASE.dfu kernelcache.release.k48 and after a white screen the ipad will reboot and you can run unsigned apps.
