It seems you cannot use the iPhone 2.0 firmware without a Twitter account, so I got one. First I started by adding some developers that I think do cool stuff. But then I got to thinking, who of my friends and contact are in there? Twitter isn't great at bulk importing, so to help me, I found TwitterWho where I could mark all my contacts in my address book, copy their names, paste it into the box and off it went and found everyone. Yay! How if I can only find a way to automatically look up Facebook friends on Twitter....
