Pangea Software has announced updates to its iPhone and iPod touch games to support iPhone 4. The new updates are available for download from the App Store.

The new versions of Pangea’s games add native support for the new iPhone 4’s “retinal” display, which allows them to be played at the native resolution of 960 x 640 pixels.

Updated titles include:

• Enigmo
• Enigmo 2
• Cro-Mag Rally
• Bugdom 2
• Otto Matic
• Nanosaur 2
• Warheads
• Antimatter
• Billy Frontier
• PangeaVR

Pangea notes that while the games run on the iPhone 4 and iOS 4, they all still works on older iPhones and iPod touches running iOS 3.1.3 as well.
