It is pretty much a no-brainer to hear news that the recently released iPhone OS 4.0 firmware update has been officially jailbroken by the iPhone Dev Team, alongside video evidence to put to bed naysayers as well as skeptics. Why bother to jailbreak your iPhone this time round since multitasking has been introduced officially? Well, perhaps there are still other minor benefits for doing so, but at least one strong argument has been shot down. For those who have already jailbroken their latest iPhone firmware update, how do you find it performing?

iOS was once upon a time called iPhone OS, or "operating system", which is the software that provides all the basic device functionality and is the interface between the hardware and applications. iOS was introduced with the iPhone on January 9 2007, and it was originally not intended to be programmable by third parties. Steve Jobs had envisioned that developers could create Web Apps that would run in the browser. This changed less than one year after when the iPhone SDK (software development kit) was introduced in October 2007. Today, hundreds of thousands of apps have been created for this platform. iPhone OS became iOS on June 2010. Interestingly, both iPhone and iOS were former trademarks of Cisco, that Apple now uses under a license.
