I keep reading about the problem with SDIO devices on the Thera.

Has anyone try the GPS by Brilliant?

check it out and let me know if it can't or can't work.

in the bottom of hte page:
Please Note: Devices above have been tested and compatible with SD-501. Basically, if the WinCE Device(PDA) with SDIO port and adopt the Bsquare SDIO NOW! would be compatible

SDIO Now is not supported in thera, so it will not work
