I don't think that would occur. It's my understanding that CDMA and EVDO are inherently more efficient than GSM/HSDPA.
Per MHz, HSDPA is more efficient than EV-DO (even Rev.A). EDGE can do 2.3Mbps per MHz under ideal conditions on a single sector (with frequency reuse, more like 384Kbps per sector), but has terrible latency and a limit of about 300Kbps per device under ideal conditions. There are network limitations that reduce speed further, but a data only EDGE network could actually be quite fast.

HSDPA as currently deployed by at&t does a maximum theoretical speed of 7.2Mbps per 5MHz or 1.44Mbps/MHz or 2.88Mbps/MHz if they deploy the HSDPA 14.4 upgrade.

EV-DO Rev.A has a maximum theoretical spectral efficiency in a data only of about 2.5Mbps/MHz, although that fails to take into account the significant penalty for having to have a separate 1.25MHz channel dedicated to voice and 1xRTT data.

So HSDPA and EV-DO are pretty close in theoretical spectral efficiency, with HSDPA enjoying the advantage on fully upgraded networks. (There are a few around the world, FWIW) Both are significantly better than EDGE when the reuse factor is taken into account.

Once VZW adds 30+ million iphones to their network, I'm sure you'll see a slow down too.
Sprint would cripple under the pressure too. Considering this is a company that's bleeding millions of customers, and I'm assuming the Pre hasn't made much of a difference, I find this test to be complete hooey. What people on this site fail to realize is that AT&T is 3 or 4 networks that were essentially smacked into one. They have work to do - but at least they aren't bleeding customers like Sprint.

AT&T really has some bad stats for reliability. And based on the many complaints from iPhone users about dropped calls and data sessions jumping back and forth between 3G and regular speeds, hardly surprising that the test stats backs up all the complaints in the forums here.
A good portion of those "complaints" aren't even from AT&T or iPhone users.

Personally, I'd recommend Sprint for reliability over VZW, if I went by the results.

VZW has typically had reliable connectivity, but is a painful company to deal with on both personal and business level.

another reason exclusive contracts shouldn't be aloud. Matter of fact I'm typing on my iPhone as we speak. I just wounded if the gov did come in and say no more exlusive contracts then how crippled the phone would be from one carrier to the next]]> http://www.dslreports.com/forum/remark,22628516 Mon, 29 Jun 2009 13:27:54 EDT Re: Surprised? http://www.dslreports.com/forum/remark,22628431 jmn1207 : It's a bit confusing for me to try and keep up with, but this is generally how I believe Sprint's roaming agreements work with regards to Verizon.

On my BlackBerry Curve with Sprint, I only show "1XEV" when I am connected to Sprint PCS, and when I roam off Sprint PCS, I only see "1X" maximum.

According to my BlackBerry manual:

D = text only (maybe voice)
1x = voice/text only
1X = slow data
1XEV = fast data

I seem to recall that the roaming agreement with Verizon allows for the Sprint Powervision stuff to work when roaming. This includes their TV and radio stuff, but it would not include general web surfing or downloads/uploads.

The exception would be with Alltel, which is technically Verizon now, but there was already a 3G data roaming agreement in place which Verizon honored after the Alltel acquisition.]]> http://www.dslreports.com/forum/remark,22628431 Mon, 29 Jun 2009 13:15:19 EDT Re: Surprised? http://www.dslreports.com/forum/remark,22628104 OverModded :

P.S. I have roamed on 3G in my area. Was it on Verizon? I can only assume that is the case given the dominance of Verizon EVDO in my area.

As far as I know, Sprint and Verizon do not have 3G data roaming agreements. When Verizon lit up there 3G network here earlier this year, I was perplexed as to why my Sprint phone was still stuck with the old data speeds when roaming. I asked on the Sprint users forums and was told there is no roaming agreement for 3G between the two carriers.

I don't think that would occur. It's my understanding that CDMA and EVDO are inherently more efficient than GSM/HSDPA. Additionally, you can roam on any CDMA/EVDO tower whereas AT&T (for the most part) has to go it alone. Verizon has the luxury of roaming among Alltel (now Verizon) and Sprint towers.

It's not like this is new to AT&T anyway. I performed a HUGE migration of worldwide users to a BlackBerry system and I had numerous people returning AT&T Blackberries because their service was awful.
I really can't disagree since I don't have a very good understanding of the technologies.

But it's something we'd have to wait to see.. 2010.. maybe.
