It was indeed disheartening to learn a few of weeks back that the iPod touch 2G could not be jailbroken just yet as per the note on iPhone dev team’s blog. However, to my surprise, I found a video by redsn0w on youtube regarding jailbreaking the iPod touch 2G. The sad part being that it was a little complex in that it took advantage of command line manipulation. I was pleased to learn about a couple of tools a few days back that let you easily jailbreak the ipod touch 2g. Both tools provide a GUI with varying degrees of manual operation in order to successfully exploit the device. These are Voltage and cyw00d’s jailbreak helper. Both tools do the job equally well, even with the most recent release of the firmware (v2.2.1). Do make sure you follow the steps right down to the very last word or else you may not succeed. I found the voltage – booter especially helpful, since both exploits are tethered, which means that they rely on the main machine (PC/Mac) to boot the device, in order to boot the device after installing WinterBoard for theming.
Note: Do not worry about bricking your iPod touch 2G since it can be easily recovered by putting the device in DFU/WTF mode. This is done by pressing both the home button and the power/sleep button simultaneously for 10 seconds (when the device is connected to the computer you’ll hear the USB disconnection sound at the end of it) followed by releasing the power button, yet holding down the home button for another 8 seconds (you’ll hear the usb connection sound on the computer). This will put the device in recovery mode, after which you can recover the original firmware using iTunes. When iTunes detects the iPod in recovery mode, it’ll give you an option to recover it, press Shift key + recover button in iTunes and select the original firmware file to restore it to normal. At the end of this process you’ll have the option of restoring the backed up files and settings. But beware, if you do not have a backup of the original backup and applications installed, they’ll all be lost.
CAUTION: Jailbreaking the iPod touch WILL void your warranty so try this only if you’re a technology enthusiast or want more out of the device in terms of features and customization. The providers of the jailbreak software or I am not responsible for any damage to the device as a result thereof.

Look guys I would like to say I’m a kinda a wiz at these types if things, umm I have a little expierence in the whole hacking thing ( even though this isn’t hacking) but any who!?!? What I need to know is that once you jail break there’s no possible way to get it back to factory setting, or to the point where your worrinty won’t be voided, because to be honest this shit makes no sense to me….. But another question is does any one know of a few fellow MCG’s or what ever these script kiddies call us know a days!?!? I’ve been out of the whole computer/consel/gaming soldiering or ” hacking” thing for a lack of a better word.
