Question: How do I connect my Bluetooth wireless phone with my laptop, so that I can send and receive files?
Answer: Connecting your Bluetooth wireless phone with your laptop is called pairing, and I'll use a Blackberry Curve to show you how it works. You can do this with any bluetooth-enabled phone, although the menu options might be slightly different depending on the type of phone you have.
Make sure that Bluetooth is enabled on your phone. For Blackberry phones, that means selecting the "Set Up Bluetooth" application from the main screen, and then selecting "Enable Bluetooth" after clicking the menu button.
I'm assuming your laptop comes with a built-in Bluetooth adapter (or you can get a bluetooth adapter like this one, that plugs into one of your USB ports).
Next, set up your computer to allow Bluetooth connections. If your computer comes with Bluetooth, then you'll see a Bluetooth icon in your Control Panel (Start button -> Control Panel from Vista):
Double-click the Bluetooth icon and you'll see a Bluetooth Devices dialog. Click the Options tab and make sure the options to "Allow Bluetooth devices to find this computer" and "Allow Bluetooth devices to connect to this computer" are both checked.
