Without having the 4G version of the BlackBerry PlayBook at launch (and if iPad stats prove true for the PlayBook the majority will opt for WiFi-only versions anyway), most users will be looking for a way to connect to the internet when away from WiFi. For that, you simply need to connect your mobile device to the PlayBook tablet via Bluetooth. I've noticed a bit of a misconception going around that people think it has to be a BlackBerry Smartphone you tether to, but as RIM has relayed to us the whole time that is not the case.
Remember, the BlackBerry Bridge, which allows you to get your BlackBerry Smartphone's email, calendar, contacts, etc. on your PlayBook (it turns your PlayBook into a big monitor for your BB phone) is different than Internet Tethering. The device you are tethering to does need to support tethering (you'll need to confirm with your plan/carrier if there will be tethering chargers, etc.), but again, it doesn't need to be a BlackBerry. The process for setting up tethering is pretty simple, but so you don't get lost along the way we have a quick tutorial to help you get it done.
Before you begin you'll need to verify the following:
Before you get started, make sure Bluetooth is enabled on both the phone and tablet. To activate Bluetooth on the PlayBook:
Tap the settings icon on the status bar
Then choose Internet Tethering
Tap Turn On
Tap the settings icon on the status bar, then again selected Internet Tethering
Your paired device should now be listed, tap it to connect
In the drop-down list, tap a service provider or tap Add and add a service provider to the list.
Tap the service provider and choose Connect.
If you add a service provider you are prompted to create a custom profile. Enter the APN, user name, and password that your wireless service provider has given you and tap Connect.
That's it! You should be up and running and successfully able to connect to the internet through your smartphone. Keep in mind that some carriers may charge a fee for this, so you'll want to check in with them so you don't get any surprises on your bill!
