Many folks have used the MyWi app on a jailbroken iPhone to wirelessly tether the device, but if you don’t want to jailbreak your iPhone and have some spare cash lying around, you could always shell out $189 for the Nexaria BC2, an 802.11n wireless router that supports the iPhone 4, 3GS and 3G. Just hook it up, and you’ll be able to share the data connection on your iPhone with your mates in the vicinity. Of course, the fact that you’ll need to keep the device plugged into the wall isn’t too handy, especially if you’re a road warrior, but it could still be useful if you’re in a hotel that doesn’t offer free Wi-Fi.
