wondering if any unlock fusion users out there have experienced a unlock reversal. i had a 4S my mom was using. unlocked thru unlock fusion ebay store last year. upgraded her to iphone 5 restored the 4S back to 5.1.1 to sell met up with the buyer today and couldnt get his tmo sim to activate. came home pissed. checking now on imei checker sites and it does say my 4s is now locked.... ive used unlock fusion 10+ times and this is the first its happened to me... any others out there with similar experience?
