I think I just wanted to get this out there. Now, I want to say I back up this info 100%, but I could be slightly off. --- For an untethered jailbreak, the iPod needs to be able to fully functional and bootable with no assistance, period. In order to do this, some how the sigchecks need to be bypassed before the iPod would enter the kernel stage (after booting). Running unsigned code prior to the kernel stage can't be done [for now] and that means no code can be executed from the iPod at recovery mode or DFU mode. The reason previous jailbreaks worked was because there weren't as many sigchecks as there are on the 2G and unsigned code was able to be planted. Correct anything that's wrong, please, but I think it's important that the general public knows exactly what's going on so people can stop asking when it's going to be released. Either way, there are rumors that the dev team has successfully created an untethered jailbreak, but if they release it now then it could ruin it for the next generation of ipod touchs/iphones. There is heavy speculation that an iPhone refresh could happen in June or July, and they would have the same hardware as the current 2G's. If the dev team were to release an untethered today, that means Apple could find it, create some sort of patch, and then make it harder on the dev team to find another jailbreak on the newer iPhones. For now, run rs isn't exactly a pain in the ass, so I think we can all live with it, considering we aren't being charged anything for the jailbreak.
