also why doesnt the phone turn off/disconnect the 3g radio when its connected with the 4g radio?

yes, that is how it is and for a few reasons:
1) your running a fully separate chipset, cdma is built into the motherboard but wimax requires its own radio and its own amplifier, these waste more power.
2) Coverage is very spotty and signal tends to be weak, this uses more energy trying to maintain signal
3) Wimax uploading is not very energy efficient, this is fixed in wimax 2 but that is not what we have.

As for turning off 3g, using 3g uses more power then 1x..by using 1x and 4g at the same time it is conserving power. Plus what is the point of having both 3g and 4g at the same time? The 1x is there for phonecalls..if they had voice over wimax then even 1x may not be needed.
