I hope this isn't true and they either have incorrect info or are misreading it:
HTC Evo 4G Expensive To Own, Sprint Leaks New Packages
HTC Evo 4G Expensive To Own, Sprint Leaks New Packages
* Special plans are being created for the HTC EVO 4G because it is the first dual mode 3G/4G phone offered by Sprint.
* The Sprint Mobile Hotspot feature, which is explained in detail in the New Apps section of this course, requires an attachable plan code. This code carries a monthly recurring charge. The cost of this plan and the code itself will be revealed at a later time closer to the launch of the HTC EVO 4G.
So now it looks like HTC Evo 4G buyers may need to pay separately for voice, 3G data, 4G/WiMax data
