Good news, everyone! Yesterday, the unfortunate news broke that Apple was now shipping iPhone 3GSs with a modified boot ROM that would make the devices impervious to the Dev Team’s jailbreak exploit, 24kpwn.
GeoHot just announced blackra1n for Mac.
Last week the Dev Team released an update to their PwnageTool for the Mac which now jailbreaks all OS 3.1 devices. Today it was announced that a Windows jailbreak is also on its way from another source.
