It took me about 2 and a half months to get it unlocked.
I got the 1.1.2 version with bootloader 4.6... (the good old days, now all in memory).
the unlock was brought out in February (if I can remember correctly). the actual process of unlocking took about 10 minutes. then came 1.1.3 which you had to do it through a "software update" in installer. 1.1.4 was easier with all the computer-based programmes doing the clicking & unlocking.
