XDA has put together a list of tricks for the Touch HD, many of which actually work on the Diamond and Pro as well. Here are the ones we found most useful that work on all three devices:

1. When viewing a photo in the HTC photo viewer, once zoomed in, tap and hold the image to get a white selection box that shows you where you are on the image.

2. Speaking of the HTC photo viewer, you make a circle with your finger to zoom in – but what you may not know is that small circles zoom in more, while a large circle zooms in just a little bit

3. Get the hidden weather animations on TouchFLO 3D, and impress your friends

4. To see more contacts in the Contacts app, go to Menu > Options > and check “Shown contact names only”

5. For high resolution thumbnails of contacts in the People tab of TouchFLO 3D, assign the images from the gallery and not the actual tab

Don’t forget to check out our Diamond/Pro Tips and Tricks Guide. Most of trips and tricks within will also work for the Touch HD.
