One of the improvements with the iPhone 3.0 OS I wrote about in mid June was the ability to run peer-to-peer games. These next generation games and applications allow multiple iPhone users to connect wirelessly. Usually all that is required is to turn on Bluetooth (Settings = General = Bluetooth = On) and you are all set to go.
One of the more popular games found at the iTunes store is Flight Control. It might not be the most realistic game but it gives you the opportunity to play Air Traffic Controller on your iPhone and iPod touch. If you have a 3GS, 3G with 3.0 downloaded, or a 2nd generation iPod touch, you can take advantage of the built-in multi-player mode of this exciting app.
With 3 different airfields and 9 aircraft types, you can see what it's like to work the most stressful job in the world. Play with a friend and you can pass aircraft back and forth to each other. Keep as many aircraft as you can if you like the pressure of pushing tin, or if you get too busy just hand off a bunch of aircraft to the other guy and see if he sinks or swims. Either way it's a fun app with plenty of options that you can now play with a friend who also has an iPhone or iPod touch.
Firemint has done extremely well with this 99 cent app and I'm sure they will have great successes with their other iPhone apps and PC games too.
