Owners of iPhone 4, original iPad, second-generation Apple TV and third- or fourth-generation iPod Touches have a limited ability to jailbreak the devices and run iOS 4.3.2, just released earlier today, with some caveats and drawbacks. A "tethered" solution, meaning the jailbreak must be re-performed after each system reboot, is available using a modified version of a third-party utility called PwnageTool and a second helper called tetheredboot utility.
