Mac iPhone 3GS unlock tool
George Hotz, creator of purplera1n, the first iPhone 3GS jailbreak tool, has announced that a Mac version is now available. In his blog, Hotz explains that he is not familiar with Mac coding and gives credit to AriX and westbaer for the port. The hack is still considered to be in the beta stage and users are reminded to backup any important data before attempting the unlock. The file weighs in at 458 KB and is available on the purplera1n website.
Pwnage Tool 2.0 released
On Saturday, iPhone Dev Team released its own utility to jailbreak and unlock the iPhone 3G, allowing users to access to the file system, to run third-party applications, and also unlock the device for use on any GSM network. The new Pwnage Tool 2.0 both jailbreaks and unlocks older iPhones as well as jailbreaks iPhone 3Gs and iPod Touches; it is designed for v2.0 firmware only, according to the brief announcement; however, a more full announcement is expected later. The free software featuring both 'simple' and 'expert' modes, patches the original Apple firmware/software download to allow users to install software and requires that users restore their iPhone using the patched IPSW file. The software appears to unlock original iPhones only and will not (yet?) unlock the iPhone 3G, which some other vendors have claimed to offer.
iPhone 3G unlocked
Less than a week after the iPhone 3G launch, a hardware-based unlock has been announced for the new phone. Gizmodo describes how the process works using the SIM card. Utilizing a special card on the back of the iPhone 3G SIM card, the phone is fed a forged International Mobile Subscriber Identity (IMSI), tricking the phone into working on a different network. The hack is confirmed via video, but not currently available.
