I have finally purchased the HTC HD7 handset which is based on the Windows 7 Phone OS after your recommendation on Best Windows Phone 7. Now the question is that how can i uninstall a application which is already installed in the handset.
In order to get started you will have to remove this application completely from your device and also from the Applications Tile.
First of all you need to swipe left on your Applications Tile which would display you all the apps in shortcuts. Next tap and hold on the application which you would like to remove from the device.
Next tap on the uninstall option and it would be removed completely. You can also rate and review the same if you are interested which can help other win 7 phone users.
