Did anyone actually unlock, relock and after that sucessfully update using either OTA or the Companion?

I can't try OTA myself. Although I'm on 7.0.A.1.303 I believe my device isn't completely free. It's optically/visually totally unbranded but a google search after my SI 1265-1624 revealed some russian site or so where I could spot the name of my provider in conjunction with the phones name. So I guess it's at least somehow provider tied (yet sim unlocked/sim free) as I also haven't got any update notification yet.
