I just got my 3G S last Friday. It's my first iPhone but, before that, I had the first gen iPod Touch. I was just comparing them side by side today and noticed that my iPod Touch screen was much brighter; like twice as bright. My first thought was it might be some setting, but the "brightness" slider is in the middle for both devices. I then thought it might be something with the Auto brightness adjustment, but I turned off the "Auto" setting on both the iPhone and the iPod and nothing changed. My iPhone is still completely usable (and if I hadn't compared it to the iPod, I don't know I would have every noticed there was anything "wrong"), but I was a bit surprised by the difference. Any insights?
