redsn0w 0.9.6b4 jailbreak targets iOS 4.2.1

By Edwin Kee on 11/23/2010 03:33 PDT

The Dev-Team Blog recently updated their page, touting a spanking new redsn0w version 0.9.6b4 jailbreak that will cater for the hot-out-of-the-oven iOS 4.2.1. Jailbreaking the device, however, is easier said than done since the 4.2.1 jailbreak is currently “tethered” so owners of the iPhone 4, iPad, and newer iPhone 3GS and iPod touch will need to hook it up to a computer to boot into a jailbroken state every time your device runs out of juice, or requires a reboot. Hmmm, seems to sound like the T-Mobile G2 where rooting it was temporary until recently, where a permanent solution was discovered. To know more about rooting or jailbreaking, head on here and here, respectively.

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.
