Mobile phones application (Java ME) which shows the upcoming events, task and a background image you desire. It can also be used as a wallpaper application in Sony Ericsson phones. MobyToday (which is a very nice application) does the same. This is an open source application. You may download the code and fix, customize, or simply learn from it.
Missing features:
1) Does not show recurring events.
2) Does not support animated GIF background.
3) Can not recognize 'all-day' events. Those events are treated as full day events.
Support about this application can be done using the forum thread at Lasyk.net.
Phone requirements:
1) Java JSR-75 - lots of phones support this feature.
2) Stand-by application support - if you wish to run it as a wallpaper. Stand-by supported phones (supposed):
W830, W850, W880, W610, W710, K610, K800, K810, K550, K790, Z310, Z610, Z710
Tested on:
K610i
Current version: 0.0.40
Source Code (A NetBeans 5.5.1 project): source code Compiled JAR, JAD.
Version 0.0.40:
1) Bug fixes - Right-To-Left - Hebrew events will be RTL while others will be LTR.
2) Configuration - You can discard errors, the error causing events will be discarded from the view.
3) Note - if your GUI freezes, changing the background image (or removing it) helps, sometimes.
