I have a recently Jailbroken ipt2g MC, and I followed the advice from a sticky here to enable wallpapers on it. My question is, does it put a drain on battery life versus not having a wallpaper at all? If it does, in your experience, how significant is it? Bear in mind that I have only had this iPod for less than 2 weeks, so I can't speak much about its native battery life. My guess is that it would have a slight, but not noticeable impact on the battery life. I'm also assuming that having it on would take up some RAM on the iPod, but that shouldn't fluctuate too much seeing how it's a constant background.
