A new jailbreak for iPhones, iPads, and iPod Touches has been released, mere days after of the iPad 3G release in the US. Called Spirit, this hack lets you jailbreak your Apple mobile devices without connecting them to a computer. While this isn't a carrier unlock (the iPad 3G has no carrier lock, and has been hacked to accept a trimmed-down T-Mobile SIM and natively send SMS), the jailbreak lets you get applications from sources outside of the Apple App Store and otherwise customize your iPhone or iPad experience.
A word of warning from the Spirit hackers: if you've jailbroken your phone using a tethered method, you have to first perform a restore before you invoke Spirit. Also, jailbreaking with Spirit is unadvised if you've unlocked your iPhone 3G or 3GS: Spirit will make it impossible to unlock your phone again as it upgrades your baseband. An initial sync with iTunes is also recommended to backup your photos (as the jailbreak is in beta, some bugs are still being worked out). Redmond Pie has the directions you'll for jailbreaking with Spirit.
(PCWorld takes zero responsibility if this jailbreak bricks your iPhone firmware-running devices, or if an image of Steve Jobs appears on the touchscreen and admonishes you to not hack proprietary hardware.)
