Jailbreak iPhone Apps
Apple's SDK and iTunes App Store rules have prohibited apps
that exploit certain iPhone
features, such as global UI enhancements (such as copy and paste), video recording and streaming, multimedia SMS, Bluetooth file sharing, Internet tethering, and background processing. Apple also blocks apps that don't fit its vision for iPhone usability, including podcasting, direct GPS access, and competing e-mail and Web browser clients. The following 21 apps today run only on jailbroken iPhones. Some of their capabilities will ship with Apple's 3.0 iPhone
firmware, but most of them won't.
