I think it's a farce and as you'll see by this device and any others on their "4G" network, it will come to bite them in the *** eventually. So when AT&T starts up their LTE network, what are they going to call that?
I'm not sure what you mean by Verizon not having a true 3G network..??
the G in these networks isn't about speed IMO.. it's about the technology behind the network. 3G = third generation.. it doesn't mean 3.6Mbps, or whatever. CDMA EVDO RevA is a third generation technology, aka 3G.
LTE/WiMax is a fourth generation technology.. aka 4G.
All the carriers are doing by calling HSPA+ "4G" is confusing the consumers.. no one is going to see 30Mbps on these networks ANYTIME SOON.
Engadget says it best.. "fake 4G"

I went to the ATT store to pick up an Atrix this morning, I ran speedtest side by side with my iphone 4 on the same server location, pulled 5.09mbps down, 1.52mbps up with the iphone, the Atrix did 1.57mbps down, 0.14mbps up. The employees at the store were shocked, I let them run them both a few more times with similar results. The best down the Atrix did was 2.5, best up was 0.6, on different runs. The phone itself is very impressive, but that choked down data speed is a deal breaker after getting use to my iphone's speed. Hopefully the issue will get resolved by ATT or through rooting, because I would love to pick that phone up.

something is definitely up with the data and i'm blaming AT&T, not the Atrix.
my iPhone 4 would regularly have download speeds between 4 and 5 mbps, sometimes eclipsing 5. Download would be 1 to 1.2
Atrix-Download speeds are decent, average around 3.5, but this is supposedly a "4g" device. Technically HSPA+, or enhanced 3g, but still the iPhone 4 is HSPA 7.2, not hspa+. This device theoretically should be cranking out higher download speeds than the iPhone 4. But I can live with 3.5, especially compared to my DX on verizon which is usually around 700 to 1.2
Now the bad part of course, the download speeds. I'm maxing out around .3 mbps. We all know the issue here by now. Same as the Inspire "4g".
I'm in Dallas where the backhaul deployment is supposedly complete. This phone right now is a 3g phone thanks to AT&T. Hopefully they don't ruin this phone. I'm gonna give it a while and see how it improves, otherwise hello Thunderbolt.
Other than the data failing to live up to expectations, I think this really is an outstanding device.

I think you're mistaken on this ..at&t is the one that. Doesn't. Have true 3g coverage ..everyone knows their network runs off of wifi signals primarily..their. 3g is minimal and spotty. Why do you think people complain so much about loss if signal? Where as Verizon atually has the best coverage out there..it always beats out all other carriers every year come reviews time..can't do that. W/O a TRUE 3G network..

i had the Evo for 30 days. Wimax was a joke imo. I'll take HSPA over it. weak building penetration due to the higher spectrum is the deal killer with wimax imo (and also the battery killer). Dallas is heavily blanketed in WiMax but it varied wildly from one street to the next. I was getting 8 mbps speeds which was nice but that was a rarity. LTE will rule all networks once fully deployed. It will be nice when AT&T and Verizon's networks are both up and running. Anxiously awaiting that Samsung LTE mobile hotspot on verizon.

Where'd you get your info from?
I'm pretty knowledgable about cellular networks and can even break it down for you spec by spec, connection by connection and I've never heard it uses WIFI.
The reason you lose signal is because GSM handoff's are what's called a "hard handoff".
CDMA networks, you're almost always connecting to 3 towers and their handoff's are called "soft handoffs". During a hard handoff, you're basically being thrown randomly to another tower where the connection get's iffy.. during this time, you may experience a dropped call.
http://en.wikipedia.org/wiki/HandoverA hard handover is one in which the channel in the source cell is released and only then the channel in the target cell is engaged. Thus the connection to the source is broken before the connection to the target is made—for this reason such handovers are also known as break-before-make. Hard handovers are intended to be instantaneous in order to minimize the disruption to the call. A hard handover is perceived by network engineers as an event during the call.
A soft handover is one in which the channel in the source cell is retained and used for a while in parallel with the channel in the target cell. In this case the connection to the target is established before the connection to the source is broken, hence this handovers is called make-before-break. The interval, during which the two connections are used in parallel, may be brief or substantial. For this reason the soft handovers is perceived by network engineers as a state of the call, rather than a brief event. Soft handovers may involve using connections to more than two cells, e.g. connections to three, four or more cells can be maintained by one phone at the same time. When a call is in a state of soft handovers the signal of the best of all used channels can be utilised for the call at a given moment or all the signals can be combined to produce a clearer copy of the signal. The latter is more advantageous, and when such combining is performed both in the downlink (forward link) and the uplink (reverse link) the handover is termed as softer. Softer handovers are possible when the cells involved in the handovers have a single cell site .

i think dial up is faster than my cell speed...sprint data card..at&t phone..speeds are just getting worse.. thinking about going back to dial up ..save a bunch of money
so much for the fed govt's push to get mobile speeds in line with rest of the world
