Blackra1n, iPhone hacker George Hotz’s software for 1-click jailbreaking, has been released for all existing iPhone and iPod Touch devices. However, it will NOT unlock the device, enabling it to be used with different GSM carriers worldwide.
Blackra1n is currently compatible with Windows only — or “all Windows that matter,” in GeoHot’s words. I am supposing that means Windows XP, Windows Vista and hopefully Windows 7 RC. Currently, there is no word on a Mac version — but it should be released soon as well.
What blackra1n does is…
Although it does support iPod Touch 3G, there is only a tethered jailbreak for it, which means you need to use blackra1n every time you boot the device.
The sudden change was the result of a last minute problem – the exploit used doesn’t work ‘properly’ on the device. It will add an extra 30 seconds to the booting process but the bigger problem is you’ll always need to be close to a PC to boot up the device, or you loose all your jailbreak data including application, themes etc.
