I don't think that the screen resolution has anything to do with it.

I know that the 3Sixty.2 App worked on the HTC Touch, but that is because it had the Microsoft Bluetooth Stack. Here are the requirements for the 3Sixty.2 App from Rockfords site:

In order to use the 3Sixty Windows Mobile software, you must meet the following requirements:
• .NET Compact Framework 2.0 or newer
• Display Resolution of 320x240 (QVGA) or 640x480 (VGA)
• Microsoft Bluetooth Stack

I don't think the HTC Touch Pro 2 uses the Microsoft Bluetooth Stack. I am unsure which one it uses exactly but remember seeing somewhere it wasn't by Microsoft.

This is the error I am getting when I run the App (after pressing details):
3Sixty.2.exe
TypeLoadException

at MyProect.Discover.PopulateList()
at MyProect.Discover..ctor()
at MyProect.Discover.Main()

Not really sure if this will help in getting this to work on the Touch Pro 2.

It's not a huge pain lugging my laptop out to my car, or I can use my old decommissioned Touch. It would be nice to have all my apps running from my current phone though!
