A few Google searches yielded no credible information for me, but I am looking for information on what I presume to be the proximity sensor, which is glowing red. I have never noticed this on any of my previous iPhones, nor did I notice it last night. I use my phone in the dark quite often, and would have certainly noticed this before. I see no problems with my phone, aside from what I think may be a rapid battery drain (possinly from my Rdio app), but if anyone has information on this, I'd appreciate it. Thanks!
