Hi, I had the same worry as I had bought my phone from eBay. I can tell you that mine is still unlocked after LGNPST and flashing the different ROMs and Kernels, but your phone could be unlocked in a different way (probably not, but I am not sure, my phone came unlocked), so I cannot guarantee it. Hope this helped
