I tested this on my Treo 650 on Verizon and it does work if you have a solid signal.
Make sure you have bluetooth turned off or it won't work.

thanks for mentioning the Bluetooth radio has to be off for Treo 650s
That solved my problem!

Are you planning on acknowledging the work of Johnnie Warner (an employee of yours) who recently passed away and did such a wonderful job of sharing his love of Palm Products with the Palm Community on his blog?
Thank you.

People on the slingcommunity forum are reporting it working on any device running PalmOS 5.4 or greater. Ones reported so far include the 680, the LifeDrive and the TX. I have the TX and it performs well. It was designed to run on a treo so it doesn't use the full screen of the TX. Therefore I still see no reason to "upgrade" to a treo.
