Thanks for posting that! I have read this section of the new manual several times but I guess I just didn't retain the fact that 3G is actually turned off when using Wi-Fi. I thought that it just used the Wi-Fi connection instead of 3G. I guess I was focused on the part in the manual that says when you turn Whispernet off your are turning off both Wi-Fi and 3G and there didn't appear to be any way to turn off just 3G.
If 3G actually does get turned off if the K3 is connected to a Wi-Fi network that might mean that if I left Whispernet on and my K3 was connected to my home wireless network the entire time that the battery should last up to three weeks just like the Wi-Fi model.
The reduced battery life for the 3G+Wi-Fi must be due to the fact that if you aren't actually connected to a Wi-Fi network the 3G is still on and using more battery power.
