iJailbreak 0.5.1, an update to iJailbreak 0.5 is now available giving iPhone users with the 1.1.3 firmware the ability to open up an iPhone with v1.1.3 installed in order to implement custom apps and services.

This latest Jailbreak requires the use of bootloader 4.6 and won't function with any other version. The 0.5.1 build is believed to have fixed the previous PowerPC-based Macs, which resulted in segmentation fault errors.
