a thing I discovered for proper experience, models version 1 and version 2:

3510,3510,5100,6100,6310,6310i,6510,6500,6610,7210,7250,7650,8310, 8910,8910i > V.1

3510i,1100,3100,3200,3300,3530,6800,6820,7250i,6220,6200,3650,3660, 3620,7200,7600,6600 > V.2

it is what I know so far, has worse thing that to be typing code and it does not function? later it gives the screen of: "he is not possible to remove restriction" and there expensive, he is fucked, you need griffin or Prodigy you are in the salt and with pepper in the eye.
