Maemo Mapper 2 for n770

Maemo mapper 2 supports 770, and can download map easily. I am staying in Singapore, and the map I downloaded includes: 1. 1'28"04.66N/103'41"10.47E to 1'17"48.99N/103'52"04.18E 2. 1'25"29.74N/103'52"04.18E to 1'17"48.99N/103'58"57.12E 3. 1'17"48.99N/103'44"37.56E to 1'14"20.82N/103'54"15.55E These areas does not cover whole Singapore, but should be more than enough for me.
