Hi there, I have a Sprint Iphone 4S activated before Nov 11. My sim slot is unlocked. However, if I did a factory reset (delete all data and settings), I believe I would be required to activate again. In that case, do I lose the sim unlock? Since I think Sprint would push sim locks at the time of activation. I am not sure, if sprint has it in records that this phone was originally activated before Nov 11th and so the sim should not be locked. Please advice, if someone has tried re-activating the iPhone post Nov 11, and still have their sim slot unlocked.
