If someone told you could get Internet service on your laptop without connecting to a Wi-Fi hotspot, purchasing a cellular Internet card, or paying additional fees through your Blackberry’s wireless network you’d want to know the catch, as well as the cost.

The only catch is that you need to already have a Blackberry with a flat-rate data plan, the USB cable that came with it, and fifty bucks. That’s how much it’ll cost you to download Tether, an app that once installed on both your Blackberry and laptop, will permit you to tether the two devices with the USB cable and start surfing the Web on your laptop.

Seriously. It works. Simply connect the two devices with the cable – make sure your laptop’s wireless card is disabled, because you won’t need it – and fire up the app on both devices. Status windows on both will acknowledge the connection and you’ll be ready to surf. That’s it. Tether connects via Bluetooth, too, but the wired way yields a more reliable connection. So Tether up and enjoy the ability to surf anywhere where your Blackberry already gets service. The first place we’d recommend? On a quiet bench at the park, blocks away from that stuffy coffee shop with its pay-per-minute Wi-Fi.
