Wait and see, I think their statement succeeded then

. You may reconsider canceling if there was chance they may change their mind, you would wait and see.
Root is one thing. That will happen, there are always things they can do. However I dont believe that full root will ever be obtained without the eng bootloader and the key. You will be flashing "roms" instead of roms

.
Do you think someone will crack the 256 bit encryption? I dont see that happening, its actually as far as I know impossible. Would you like to see the total possible combinations from a 256 bit encryption?

and added a link:
For cryptographers, a cryptographic "break" is anything faster than a brute force attack - trying every possible key. Thus, an attack against a 256-bit-key AES requiring 2^200 operations (compared to 2^256 possible keys) would be considered a break, even though 2^200 operations would still take far longer than the age of the universe to complete. The largest successful publicly-known brute force attack has been against a 64-bit RC5 key by distributed.net.[10] (its a wiki but its accurate)
