Hello there, do these shsh need to saved to the PC?? Or the ipad itself?? But if the ipad jailbreak is not out yet how can it be saved using tinyumbrella which is availabe thru cydia
Tinyumbrella saves them to your PC and puts a request to have them saved on Saurik's (Cydia) servers as well. Saving them does not rely upon a jailbreak.
The SHSHs allow you to downgrade firmware since firmware updates send a request to Apple's servers. "Can I install this firmware?" Tinyumbrella and/or Saurik's servers mock the Apple server allowing you to install older firmware as long as you have SHSHs saved for said firmware.
