My 4S heats up slightly after few minutes of 3G downloading, is this normal?

What I meant was that the 'yellow' screen most people are complaining about are actually just the way it's supposed to be. Some units however, are too yellow, to the point where it's really annoying to look at. For example, there was a video a forumer posted yesterday comparing the yellow display on the 4S to the i4. Now, that is a serious issue cuz the screen is really really yellow. Even without comparing, you can see that the screen quality sucks.

However, my screen is not even close to that color. It's just warmer, not even fair to say yellow.

Just a noob question..just got my phone and found out that it is 5.0 ios...reach home,  set it to wifi and connects to my itune. Check for ios 5.0.1 from the internet (thought of download and install it). Then i found out there is a software update thing in setting...and when i click it, it already said downloading 5.0.1. without me doing anything. It was actually great but i just worry will it auto help me download the latest version next time which will eats up lots of my 3g data (when not connected to wifi)?
