Q: Can I use the Bluetooth connection from my Treo to my Laptop (and then the Internet) instead of the GPRS or CDMA phone network?

Yes! In fact, in this configuration you don't have to worry about Internet data charges from your mobile operator, and you'll get much faster upload rates. Often, an image can upload in 1 second or less (depending on network speeds)! We have not tested Windows Mobile or other devices in this configuration, but as long as a device can use a Bluetooth connection for Internet access, then it "should" work.
