worldmap is an J2ME OpenStreetMap client using online OSM data.

Usage

• Use the 4-way-buttons (or '2', '8', '4' and '6') to move around on the map.
• Use '5' (or Enter on some phones) to zoom in and '0' to zoom out.
• Press '1' to center the map on the current GPS position (if it is available).

Requirements

• CLDC 1.1 (JSR 139)
• MIDP 2.0 (JSR 118)
• Java API for Bluetooth (JSR-82) (optional for external GPS receiver)
• Java Location API (JSR-179) (optional)

Hardware reference phones are the Nokia 6300i and the Sony Ericsson K610i. Others will probably work. Some sort of traffic flatrate is highly recommended as the app uses online maps.
