Easiest unlock ever (works on i780 and Omnia):
1) Download attached ZIP file
2) copy all three .lnk files to your PPC
3) run Lock.lnk
4) enter valid MCC/MNC of any carrier (I used my "real" SIMLock carrier ID, list:
http://en.wikipedia.org/wiki/Mobile_Network_Code ; eg. 26001 for Poland, Plus)
5) As NCK, enter 12345678
6) tap OK (it should tell that SIMLock enabled)
7) run Status.lnk to see if its locked
8) run Unlock.lnk
9) enter code entered in point 5 (12345678)
10) voila
Alternative method, works on i780, no copying of anything required:
