You can install PdaNet+ directly from Play Store. However some carriers such as Sprint and AT&T may have delisted PdaNet+ from Play Store
to make users pay for their tether plan. As a result
PdaNet+ will not show up in search results or will say "incompatible" in Play Store. To solve this issue,
you can install the apk file from phone browser at http://pdanet.co/bin. Or simply install on the
computer side with instructions below, it will push PdaNet+
to your phone automatically.
To use USB mode you need to install PdaNet+ on the computer side. You can download the installer
on your computer or even using your phone if your computer does not have Internet access yet before PdaNet+ is installed. Just
go to http://pdanet.co/a on your computer browser or phone browser.

If you have already installed on the computer side, you should see a PdaNet icon in the tray area (bottom-right of your computer screen, make sure the tray area is expanded). Click on it and select "Connect" to start the Internet connection.
Alternatively, when you plugin your phone, you should also see a PdaNet flyout on the computer side asking you to connect.
In order to have both versions of PdaNet on the computer, you will need to install the Android version first then make a copy of folder "c:\program files\PdaNet for Android". Now install the other version. After the installation you will end up with two PdaNet directories, one for each phone. When you switch phones, make sure you exit PdaNet on the computer end then run the corresponding exe under the correct directory.
