added unlock code request for w100 mobiles - and that is just start.
- we need special 12-digit serial number, NOT IMEI
- that special number can be readout during identify procedure for w100, starting from 1.088 version
- put 12-digit serial number in serial field on locks tab, press "request" button. if serial can be found, you will receive codes.
- cost of successful request - 1 credits.
