The iPhone Dev team have released Pwnage Tool 3.1.5which can create iPhone 3.1.3 custom ipsw files. This latest version of PwnageTool can jailbreak the original iPhone 2G, iPhone 3G, iPhone 3GS(older bootrom only with baseband 04.26.08) and iPod touch (1G and 2G non-MC model) running on iPhone firmware 3.1.3.
The custom .ipsw firmware files created with PwnageTool can update iPhone to firmware 3.1.3 without updating its baseband so that it can be unlocked to run on any carrier SIM. Interestingly iPhone Dev team hasn’t used any new exploit to jailbreak 3.1.3 firmware and is straightforward port of Pwnage2 and 24Kpwn to the new firmware.
