I will use this post as a repository for my favourite Windows Mobile Applications:
AE Button plus
This utility extends functionality of hardware keys on Windows Mobile devices. It allows you to:
As a result you may “convert” volume slider to up/down arrows, assign several essential application buttons to these “SoftKey” buttons and even assign your favorit alternative dialer to red/green phone buttons.
G-watch is a stopwatch/countdown that uses your built in GPS to track how much distance you have covered running/cycling/driving. It is really really cool. It is still a beta version but worked very well for me. On my way to my training I uploaded that application to my phone and was happy to finally know my running speed and the distance I ran. This will be great to set goals and improve my running speed.
Ok that one is not really an application but you can find the steps to allow the BBC Iplayer on your HD on the following website
