I read over at Palm Infocenter that June Fabrics PDA Technology Group has updated PdaNet for the Palm Treo 700p, 755p and Palm Centro. Version 4.12 is now available.
With PdaNet, your computer (Windows only) can go online by connecting to your Treo or Centro through the Hotsync USB cable or Bluetooth. If you have a data plan with your Treo or Centro, preferably unlimited data, PdaNet can make it your wireless Internet Connection for your laptop/desktop computer instantly, with no extra hardware or setup being necessary.
PdaNet version 4.12 for Treo 700p, 755p and Centro supports high-speed data. In the PdaNet settings, there is a box you can check for EVDO Boost. This can potentially double your download speed.
PdaNet is also available for the Treo 650, 680 and Windows Mobile devices too, including the Treo 800w.
You can download PdaNet for free but the cost to register the product is $34.00.
