Sorry, but it's not the battery. It's the portion above the battery. I'm guessing that's where the processor might be.Whenever you drain the battery at a good clip (Wifi + GPS for example), The battery will get hot. You can blame physics for this problem, if you would so like.
OK lemme rephrase- If you tax the processor, it will get hot. If you use 3G for an extended period, it will get hot. If you use GPS for a while, it will get hot. If the battery drains quite a bit in a short period, it will get hot. Screen and speaker shouldn't get hot. It's normal in the smartphone world. You will get used to it. It's actually a good notification of how much you are taxing your battery.
Yes, but we're curious people( I am at least ) and we'd like to know the exact part that's getting hot. I do agree though, if you do things that use a lot of energy, it gets hot.
Perfectly normal. If it gets warm while you aren't using it, then you can start to worry.

I actually noticed this today. It was warm in my pocket today for some reason. I think something was running I wasn't aware of.
