I don't understand what the big deal. It is clearly documented that if you have a replacement device, you need to contact them with proof and they will provide you with new unlock.

They needed to cover themselves from people selling unlocks on ebay and have been nothing but fair with my experience with them. Have any of you tried contacting them on XDA? That's their main board.

Quoted directly from the unlocker post, "Licensing information: it's like with previous Hard-SPL unlockers - every user gets one free use of the Hard-SPL, further use is subject to paying 3GBP per each device.
however, if you are a private user, you can have other uses free on request if needed, such as using it on a replacement device.
the license is valid forever and all this works as transparently as possible, so for normal users nothing is noticable"
