Mine doesn't get hot at all when charging.
1. Battery discharge/charge is very inefficient, with more than 30% loss due to heat. Also it has electrical resistance etc that causes heat to escape.
1b. The faster the processor, the more it over heats. Read up on wiki about the size of processor vs thermal limitations.
2. Iphone 4 is made of a glass that dissipates heat faster than the older plastic models (3g and 3gs), so it'll feel hotter.
3. It is better that the heat escapes and cools down the main chips, so if it bothers you, then I recommend you get a case.
When you google this, there is a link on apple's website that states to take it out of its case while charging. Some cases will cause this. My wife and I both have iPhone 4s and while mine doesnt get hot while charging (my phone has a bumper) hers does (her phone has a full case) Hope this helps someone.
