Pretty cool app out there called Ahoy and Ahoy! Lite which allow sharing contact information directly between iPhone or (Internet enabled) iPod Touch. Basically it works by selecting a contact from the Address Book and then pushes that data into the cloud where another user can see the shared entry and add it directly to their address book. Here are the screens. The "Add a Contact" tab shows who is sharing their information. The "Share Contact" tab allows the user to pick an address book entry and share it with the world (until they close the app). It cleanly solves the missing bluetooth contact exchange feature prevalent on other platforms and makes it easy at the same time. You open the app, select a shared contact and add it or share your contact information and the receiving user can add your shared information. Makes it easy if you meet someone at an event and you don't have to tediously text or otherwise add the contact info by hand. Sure it's probably missing a few features but it definitely does the job. Here are the App Store links. Ahoy! Lite (Free) Ahoy (Currently $2.99) The free version only allows sharing an email address, name (or company), and phone number. That probably accounts for 98% of my address book. The pay version allows sharing extra information such as addresses and links (home page etc.) and attaches the image (if there is one) from the address book entry.
