Premium Data to have higher 3G/4G priority?
According to a Sprint employee who works in a network management group at Sprint HQ, EVO (and any future devices with 'premium data' accounts) will have higher 3G/4G priority than 'standard or pre-paid accounts'. Premium Data isn't really EVO specific, it's just the first device to have it.
Take with grain of salt but that's what he claims.

I believe it could be true and here is why.
In 3g land voice and data are on seperate connections. In 4g it is all IP so voice and data travel on the same pathway- voice and data are all packets on the network. This type of architecture is how most business T1s are provisioned these days. Provider delivers a data T1 (I am not using the word Internet very intentionally here) and it is a private connection to their network. The carriers core network then determines if the packets are voice or Internet and routes them to the softswitch in the case of voice- or the public Internet and the case of Internet.
The most important element to ensure good voice quality in network like the above (VoIP network) is the ability to identify what packets are voice (and need special prioirty) and which packets are data and don't. Multi prototocol label switching (MPLS) is what is used to do this. Sprint runs a pure all MPLS backbone so they can queue traffic how ever they want.
So- when you are talking on the Evo your packets will absolutely have priority over other users data (including other Evos surfing the web, youtube, etc) . The question really becomes wether Sprint will prioritize "standard" data coming from the Evo over other 3 g devices. They certainly could do it- not sure if they actually will.

Well you are stating a given fact, that QoS is used for a mixed voice+data stream over an IP network... but that is not what is being stated here...
what is being stated that EVO data will have a higher priority than (say) blackberry data on a 3G network..
this is not a wise strategy and i would need to see some evidence rather than just a glib statement by someone to attempt to mollify a user.. if true i could argue that a 89.99 plan user should get higher priority than a 69.99 user, or a full price over a discounted plan, or a 10yr customer over a new customer.. its a bag of worms..

The thing is that isnt the case in Sprints network. No voice is EVER going over Sprints 4g network. Sprints 4g network is DATA only and that is the same way that LTE is going to be for Verizon and AT&T. They havent figured out how to get voice to work over LTE. That is exactly why Dan Hesse stated that you can ONLY do voice + data at the same time when you are on 4G network/wifi, so data goes out 4G/wifi and voice still stays on the CDMA sprint network the way its been doing it from the beginning.
here is an example, you are driving through baltimore, talking on the phone and checking a link for someone. then you drive out of baltimore while the page is loading and lose 4g, oops there goes your web browsing, gunna have to wait till you get off the phone and use 3g.
