I assume you are talking about a SanDisk Trans Flash card. Treos use a Secure Digital (SD) memory card for memory expansion. There are adapters that allow you to use your trans flash cards in sd readers. An example of one can be found at

As both micro sd and normal sd adapters exist, make sure you have the normal sd, as micro sd will not be compatable with the 650.
Hopefully that helps
