What was needed was a resistor / capacitor to downgrade the output to the correct levels (which we now have). I imagine this is what these new phones have. I am going to do a little research and see what I can find out.

A laptop and and a phone are 2 different beasts..a laptop receives a lot more charge then a phone..The power connector is there for mostly transforming AC to DC and regulates voltage...inside both laptops and phones as long as the voltage is same are a set of resistors to regulate it, but these have an allowed range..if you go over the allowed range it can fry. USB has a standard for up to 1A so there shouldn't be any issue as 1A charging is considered.
oh compuw22c, the TP overheating thing has to do when a li-on battery starts draining and charging a lot at the same time...thus causing over heating..then once TP reached a certain heat level it deactivates the charging to prevent damage...there was a mod to increase the allowed overheating limit. In the TP2, HTC was smarter and added a thing that once it reaches a certain heat level it stops charging, waits for it to cool down and begin again to charge to full in cycles. Aka this is a flaw in li-on batteries when they charge and discharge a lot at the same time... not really the rate at which it charges, at least in this specific instance.
