i just got an ipad 2 wifi only (no cell phone tech just ipad 2) and i have tried everything to downgrade and jailbreak and nothing works.it came with ios 4.3.5 witch is not jailbreak or downgrade able.i was wondering if i enroll in the ios development for $99 and register the ipad as test device can i then downgrade to 4.3.1 or less?also are the shsh blobs unique to the device down to the serial or even contain our identity (meaning we can not share shsh blobs in order to sign for a downgrade)?i remember with the ipods 5 and less their drive could be erased by disk utility and made to downgrade firmware.i was wondering can the firmware partition on the ipad 2 be erased and then made to load a new firmware from scratch?thanks for the help
