Now, I’m not business person by any means, but I think old style business cards are cool.  Of course the plain white ones are boring and tough to keep track of unlike these.  TechCrunch thinks otherwise and just posted about a kind of virtual business card using the iPhone.  From the people who brought you Twinkle on the iPhone/iPod Touch, Tapulous has come up with a cool way to exchange business card-like information known as FriendBook.  When two iPhones or iPod Touches are next to each other, all the users have to do is shake the device and the info will exchange automatically.  How cool!
