Phone as a wifi dongle

[lgoldstein83]

So this might be a wierd thing to try. I have an old Droid X sitting around the house. I recently bought a Raspberry Pi and want to use it as a media center. The problem that I have is that I don't have an easy way to plug a network cable into it. What I want to do is tether the Pi to my phone, using the phone as a wifi dongle. I don't have data on the phone so that is not what I'm looking for. Any ideas would be great. Thanks!
