For those of you with jailbroke iPhones, you might be interested in the new iDongle, a DIY stand-alone device that will allow your jailbroke iPhone to tether boot when you iPhone runs out of batteries or resets due to a software bug.
A neat little device I’d say. I am sure the author can extend the functionality to even jailbreak an iPhone in the future. These are on limited productions as it seems now but may become more popular among iPhone hackers soon.
If your jailbreaked device is stuck into “recovery mode” (i.e Connect-to-iTunes logo) each time you restart or reboot your device, then it may be usefull for you =)
