I bought my i300 from the same person and it works great.

You need to plug in the USB cable to the computer. Then load the USB drivers that came with your phone. On my computer the USB port is com 4. Make sure you select the correct port in the HotSychn Manager Setup. Also select Local Serial AND Local USB. Don't ask why, it just seems to work that way.

Go to Palm Website and download the latest version of palm Desktop Version 4.1.4 This version is more current then what is on the CD that came with the phone.

I hope this helps.
