Sprint Touch Pro TF3D Hacking Part 1: VGA Backgrounds
While setting a new background on your Home tab might not be a challenge, the same cannot be said about the rest of your tabs. Here’s the process:
1. Grab whatever image you want to start with, like this one I got from some forum:

Dimensions: 480(w) x 640(h)
2. Next, crop it by 50 pixels on the top and bottom to account for the start bar and soft keys bar:

New dimensions: 480 (w) x 540 (h)
3. Now you need to squash/stretch/skew it to the dimensions it needs to be to embed it in the manila file:

Dimensions: 460 (w) x 512 (h)
4. Next use Manila Editor to Export the current image in 4a087e41_manila using “Save As..”

4. Open your image in MS Paint, Select All, Cut.
5. Open the image you just exported from Manila Editor in another instance of MS Paint, Paste, Save.
6. Next, use Manila Editor to Replace the image in 4a087e41_manila with yours:

7. Open 4a087e41_manila with a HEX editor such as XVI32 and modify the first two lines of the file’s header to the values pictured below, ending with the selected box:

8. Disable the TouchFLO 3D Today Item (Start, Settings, Today, Items, Uncheck TouchFLO 3D).
9. Copy the new version of 4a087e41_manila to your Windows directory with Total Commander.
10. Enable the TouchFLO 3D Today Item.
11. (Optional) Open your original image in Pictures & Videos on your Touch, then click Menu, Set as Today Background, and change the Transparency Level to 0%, Click OK. Now you should have a background in your Start Menu that matches the one TouchFLO is using
Alternatively, you could download this file, and just follow steps 8 - 10.
