This is going to be a work in progress. By doing the below steps you take responsibility of damaging your phone in to your own hands and will not hold me or anyone else liable. I have successfully done this on my phone but have not had enough time to experiment thoroughly.

Requirements:
- SD Card Preloaded With MP3
- Windows Mobile/Pocket PC Registry Editor (Google "PHM RegEdit Download")

Steps:

1) Locate the full path of the ring tone you want to use on your SD card. You can do this either via your PC through ActiveSync Explore or via the Windows Mobile File Explorer. An example path would be "\Storage Card\My Music\File Name.mp3".

2) Launch your registry editor on the VX6700.

3) Navigate to "HKEY_CURRENT_USER\ControlPanel\Sounds"

4) From here you can choose what event you want to assign an MP3 to by selecting the next branch in the registry. An example is the "RingTone0" folder. This is for the standard incoming call ring tone.

5) Assuming you chose RingTone0, you will then need to create or modify a String Value (Edit > New String Value to create) with a value name of "Sound". So the full path would be "HKEY_CURRENT_USER\ControlPanel\Sounds\RingTone0\S o und" in our example.

6) Set the Value Data for the "Sound" to the full path you chose in Step 1. In this example it would be "\Storage Card\My Music\File Name.mp3" (without quotes).

7) Hit the OK button and hit Yes to any prompts to save this change.

Thats it. The change should take immediately with no reboot required. I have noticed if you go into your Phone > Options screen it may not let you out again unless you choose a ring tone located in your phone itself, so avoid that at all cost.
