More iPhone 1.1.3 jailbreak details emerge

Developers have now completed an easier jailbreak method (refined from the previously noted software-based method), suitable for end users, that works with iPhones running software/firmware 1.1.3, iPhone Atlas has learned. However, developers of the jailbreak method are still debating whether or not to release the method publicly before Apple’s official SDK (software development kit) is announced. Their concern: Apple may break this method when official third-party applications ship, disallowing the co-existence of official and unofficial apps. The unofficial development team wants to reuse the current jailbreak method with any software update that Apple issues post-SDK.

Jailbreaking allows full read/write access to the iPhone’s filesystem, which enables the installation of third-party applications. We’ve gleaned a few other details about the newly refined, private 1.1.3 jailbreak:

  • The method is “about as difficult” as the one used to jailbreak iPhones running software/firmware 1.1.2.

  • Unlike previous jailbreak methods, the 1.1.3 method only allows applications to run in restricted user mode. This means that certain currently available third-party applications will not run properly. Installer.app, the program used to browse and install third-party apps, for instance, requires additional hacking to run properly on jailbroken 1.1.3 iPhones.

We’ve been told that the decision to release the 1.1.3 jailbreak method before Apple’s SDK announcement/shipment is currently under debate, meaning a public outing could occur soon.
