PainMeds writes: iPhone Atlas is reporting that the first jailbreak for the iPhone 3G has been released, and includes the popular Cydia community installer for distributing free games and applications. Since Apple's SDK was released, web sites have criticized Apple for the restrictions placed on both what developers could write and what APIs they were allowed to use. Others have noted the SDK's incompatibility with the GPL. The Cydia installer has provided a distribution channel for both open source software and software that would otherwise be impossible to build using the restricted SDK. A few applications are already out, including MobileTerminal and NES.app, a Nintendo game console emulator. In just over a week, open development is finally here for the iPhone 3G!
