I picked up this little iPhone of the Future riff musing on what the iPhone (phone, Blackberry's or PDAs in general) can do or will be able to do soon. With some editing... 1. Phone as a hotel or car key. Your phone can unlock your hotel door. Or car door. A firm known as OpenWays is currently working on the solution, which would allow you to skip the check-in desk and walk directly to your hotel room, having made the reservations in advance.

2. Advanced social networking. Walk into a restaurant and look at all of your friends who have been there and read the reviews they've written. ReadWriteWeb suggests that a more realistic form of social networking could take place, allowing you to integrate social networks with your life away from the keyboard.
3. Personalized travel guides. Another interesting idea from ReadWriteWeb is the idea of a personalized travel guide. Many people take virtual tours when they go to museums - so why not download an App that offers a virtual tour of Venice? Plug in the headphones and allow the GPS to show your App where you are in Venice, guiding you to the local restaurants and historic sites while offering recommendations for hotels and other tourist-friendly activities.
4. Phone projection for video. If the iPhone came with a projector, all you would need is a screen to carry movies with you.
