Cannot receive nor send files on T-Mobile SDA via Bluetooth

[katrinaa]

I have been using my T-Mobile SDA for quite a while and have never figured out how to receive files or send them via bluetooth..
How can I send my files to other devices?
And, whenever I try to receive files, the device that is trying to send it to me gets an error message saying, "Service not supported."
Does anybody know how to remedy this? I would rather have receiving files working than being able to send files..

I have the T-Mobile Dash but I send files all the time, but I am also using Resco File Explorer. You might try the demo of it and see if it helps.
FWIW
