Hello, i'm currently running the iOS6 tethered jailbreak on my iPod Touch 4th Generation. The problem i have is that when my battery runs out, i have to reboot using the desktop computer with Redsn0w as the jailbreak becomes inactive. My laptop has Ubuntu 11.04 installed and it seems impossible to run redsn0w on this operating system. When i am using my Touch, the battery usually goes at 2% so i often plug into a power source at 3% or 4%. But more and more recently i have found myself in the mood where i can't be bothered to plug in because it means getting up and searching for the charger, and then the battery goes much to my frustration meaning my device is somewhat useless. (It's actually semi-tethered so i can run some apps, but not many). Is there an app or tweak which will automatically lock the iPod when the power gets critically low, or perhaps some combination using Activator which would work instead? Having something like this would come in very handy, especially when i am stopping at my grandparents house where i do not have my computer with me to boot up again. Many thanks, and i hope you can help.
