A purported YouTube video is doing the rounds claiming that the infamous iPhone Dev Team has finally managed to get iOS 4.2.1 to boot untethered on new-generation devices.

iOS 4.2.1 jailbreaks performed on new iPhones and iPod touches (i.e. iPhone 4 and iPod touch 3rd and 4th generation) are “tethered,” meaning every time the battery dies, or (for whatever reason) you need to reboot the unit, the jailbreak is lost, unless you start the device up tethered to a computer running the jailbreak tool.

The video clip embedded below purports to show the latest accomplishment from the iPhone Dev Team, 9to5mac reports.

Citing an unnamed source, the blog informs that the Team has managed to boot a jailbroken iPod touch (fourth generation) running iOS 4.2.1 without actually tethering it to a computer.

The source claimed the video was uploaded by none other than MuscleNerd, one of the more vocal Dev Team members who generally takes it upon himself to inform the world of their latest hacks, either by tweets, or via YouTube.

“MuscleNerd just uploaded this video booting a untethered iPhone 4. and I heard they are on their way to unlock bb 02.10.04,” the source said.

The last statement refers to the baseband that iOS 4.2.1 applies to Apple’s devices, which renders them incompatible with current unlock solutions.

Softpedia can confirm that MuscleNerd has recently tweeted his achievement, saying “ipt4g 4.2.1 untethered JB w/4.2b3 kernel: http://is.gd/inE4e ... Wastes no exploits, but upcoming @comex JB maybe better.”

In a later tweet, he reveals that a new video is on the way, after being called out by some for not following his own ‘video guidelines’.
