hmmmm
Those speeds are what you get on EVDO Rev 0 and A. And they are not going to upgrade their entire network? Isn't both sprint and verizon on the way to upgrading their entire network to REV A by the end of 2008? I thought I read sprint will have their entire network upgraded by end of 2007.

Yeah it's because of spectrum demands.
EV-DO is only 1.25 MHz on top of 2.5MHz of 1xRTT
HSPA is an entire 5 MHz set. It's not meant to compliment GSM but replace it but since a lot of people have non 3G phones, they can't get rid of the GSM from markets that don't have enough spectrum for both.
Those markets will have to wait for LTE which can run with as little as 1.25 MHz if I remember correctly.

Well I know Sprint will be Full EV-D0 Rev A by the end of 2007 and 60-70% WiMAX be the end of 2008. Its kinda funny how HSUPA is only as fast as EV-D0 and yet Sprint is already moving toward an even faster network. I currently use both Sprint and at&t and can't wait to fully drop at&t in a few months. I think I'll move those lines to t-mobile for the international roaming they offer.

Those speeds are for the uplink right. Also, I thought that thats all the upgrade was going to do was get it up to the speed of Rev A. Where they have coverage is already Rev O speed so this is just a modest upgrade i guess.
...
They will upgrade some but not sure if they will do all yet. HSUPA is pretty good on the uplink, depending on how much spectrum per carrier they use. HSDPA is the same situation. DO and HSPA differ on the spectrum usage per carrier that favors DO a little bit more because of the lesser requirements to reach certain speeds.
