it's not a hack, but i managed to unlock a couple of items within 1 or 2 days, but i can't remember exactly how i did it. but here's a basic idea of what i did.
i traded an item that was locked to my trade partner. then i equipped the gear and logged off. the next day i logged on it was announced as unlocked.
now there are more details in that. I believe that some of what i did was first unlock before trading the item.then i can't remember if i logged off and back on and then put the item in unlock. i guess u'll have to play with it. and i haven't tried since about patch 5070 or so. but it did work and it was unlocked in like one day or so. sorry i can't be more specific, but i didn't write it down, and i haven't tried since. so i've forgotten exactly what i did.
