Missing Java SE+ME support, digital compass, bigger battery support.

Alarm should be settable also manually to any spesific time before meeting.

In a month-view, somewhat quicker way to see the content of days which have meetings, (like in N95, popup-hint-window);

Battery-graph, GPS-Jinni, Password Safe, ECouch,MStarDict, BlueMaemo, FM-radio, PC-Connectivity manager.

up/down cursor keys in scandinavian version too difficult. I would move Ä to Å's place to get up+down arrows to correct places.

Volume up/down vs zoom in/out could be done with the same swing-key by having volume behind double click and zoom with little delay to see if there was the double click. Also in the powerkey-menu, a toggle-setting to zoom/volume/double.
