we are proud to release correct DB2020 unlocking via codes (red CID49/51) as the first team. Unlike other tools, this procedure does not damage phone security zone, and therefore it does not require presence of patched firmware for the phone to remain unlocked. Reflashing the phone afterwards does not cause the phone to relock itself.

From other features of Cruiser Plus v11.00 we can list:
Implemented cross-CID flashing for red CID49/51 DB2020 phones. This allows users to flash latest firmwares without having to upgrade CID.
Implemented unlock RSA operation for red CID49/51 DB2020 phones. It costs one ordinary server credit.
Old ARM (J220/J230/Z300) unlocking enhanced.
Enabled support for flashing J220, J230 and Z300 phones.
Several applets updated. [also in Cruiser]
Updated TAC list for W200i, W880i and Z558i. [also in Cruiser]
DCU-60 communication code enhanced. [also in Cruiser]
Built-in customizations updated. [also in Cruiser]
