Now v2.1 is in support area.
FAST unlock (less than 1 min.) based on patched flash.
Until now tested and work well on:
8380 V10B Italy
8380 V10B Sweden
8380 V10B Denmark
8380 V10C Honk-Kong

Please post results. Also there is not any danger for the phone, because if something not working well, phone can be recovered at initial state by flashing all files from original version(s).
