Apple iPhone 4 launch had some interesting gaming news as well.

FarmVille and Guitar Hero are two hugely popular games that are coming to the iPhone platform.

Zynga is developing a native version of FarmVille for the iPhone. The original game is coded in Adobe Flash which is prohibited on the iPhone.

This means that a special version of iPad is also likely to arrive in the future. This is big for Apple as FarmVille has more than 80 million users around the world.

Activision has launched their Guitar Hero game on the Apple App Store. It is priced at USD 3. The game is optimized for the iPhone and works rather well as we could see from the demo during the launch event.
