nitoblu: This tutorial describes all functions of XS++ for 2.x. XS++3.1 has got FSX, can handle some more phones and doesn't need bruteforce for K750/W800 because unlocked loaders were added. The XS++2.x tutorial can be used for 3.1 as well. The only function that is not described is the FSX. I haven't got the time to update the tutorial.

Simox has released a patch creator for DB2010 firmwares. I wasn't able to test it yet but it's worth a try. It should create patches for unlocking for every DB2010 firmware.
The phones supported by USBSmart 8.4 or SE Tool 2 cracked can be full unlocked for free.
