I couldn't help but check out the radio specs of the WP8 phones destined for T-Mobile USA (Lumia 820, HTC 8X & 8S, and Samsung Ativ S). All of their spec sheets list the HSPA+ network bands as 850/900/1900/2100 MHz. It is known that in order to receive HSPA+ on T-Mobile BOTH the 1700MHz and the 2100MHz bands must be supported. We know that T-Mobile is refarming their 1900 PCS band to support 3G/HSPA+ in most markets. However, we still don't know which markets they are and when the rollout will be completed. It is rumored that the refarming will be completed by the end of 2012 with LTE implementation starting in 2013 but nothing has been announced yet regarding the completion of the refarm. I'm assuming since all of the WP8 Phones destined for T-Mobile are missing the 1700MHz band support, that the OEMs must know something we don't. I was thinking of making the switch to tmo in November but don't want to have a bad WP8 experience by not having HSPA+42. Please chime in with your thoughts.....

Even after T-Mo refarms, you'll be getting single-channel HSPA with a non-AWS device. That will be 3 megabits/second versus an average of 24 to 36 using a proper AWS HSPA+42 device like one of HTCs or Samsung's WP8 handsets made for T-Mo.
The unlocked iPhone promo is strictly a value play for people who would otherwise get Sprint and their "slow-as-EDGE" 3G speeds. T-Mo isn't guaranteeing availability of HSPA for iOS devices on the 1900 MHz band.

No. T-Mobile's AWS network uses 1700/2100, while AT&T's uses 1900/2100.
Historically, this has meant that 1900/2100 devices have run only on EDGE (2.5G on T-Mo), very slowly.
T-Mobile is using a thin slice of 1900 MHz to emulate AT&T's 1900/2100 setup (which isn't supported by non-AWS/pentaband radios). As a result, 1900/2100 phones like the iPhone and 920 (as announced) will get 3G speeds for the first time on T-Mo.
But T-Mo's 4G tech uses full-speed HSPA+42 -- three parallel "pipes" of HSPA+14 over AWS 1700/2100. It will always be much, much faster than single-channel HSPA over 1900/2100.
T-Mo is also deploying LTE in 2013 (though the 8X is not expected to support it in its T-Mo incarnation). HSPA+42 gets similar speeds, but with higher latencies. Both LTE and HSPA+42 are vastly preferable to HSPA single-channel 3G on 1900/2100.
Long story short -- an unlocked worldphone without 1700/2100 WILL work on T-Mo, but at super-slow EDGE speeds (if you're unlucky and not in a refarmed area) or mere 3G speeds. I'm not sure ANY device makes up for not having access to T-Mo's full AWS HSPA+ 4G speeds, so I'd go with an AWS device over a "worldphone" without AWS support.

Any phone launched for T-Mobile USA will support AWS. Period. It's a base requirement for T-Mobile. T-Mo will NOT sell smartphones that lack AWS support.
Every handset launched on T-Mo has been modified from the international version for AWS (or is pentaband). That includes Lumia 710, HTC Radar, HTC HD7, and Android handsets like the One X and GS III, all of which were modified by the manufacturer to work with 1700/2100.
Any specs you're seeing in the 8X and ATIV announcements are for the "unlocked/international" handsets and have zero to do with the handsets specifically sold for T-Mo USA.

I don't understand why they don't release a global phone that has all network frequencies supported. They could at least do this by region (US, Europe, South America, Australia, China, etc).

And I thought that's what they do now, create phones for general regions with a some overlap in case you travel.

Yep. Certain frequencies require certain antenna sizes, shapes and configurations to effectively receive and send signals. A phone with the "wrong" antenna shape for a particular frequency will drop calls, suffer from slow data speeds, and generally not perform well.

Rumor: AT&T looking to launch the Nokia Lumia 820, 920 on November 2nd | wpcentral | Windows Phone News, Forums, and Reviews
According to Daniel in this article, both the Lumia 920 and 820 are pentaband phones so they would both work perfectly on T-Mobile if unlocked. I disagree with the fact that it is difficult to build many frequency support into a phone. All OEMs have to do is place pentaband chipsets into their phones instead of quad or triband radios. Phone makers such as Nokia have been making pentaband phones for years. I think this has more to do with carriers trying to force consumers into staying on their network and not jumping ship to cross carriers without the consumer having to purchase a new phone.

Everything I've read shows that T-Mobile is bringing their "4G HSPA+" network over to the 1900 PCS band to make room for LTE on the current AWS bands. It would be real dumb to try and move as many people as they can over to 1900 and throw aside all the work they've been doing with HSPA+42 and higher. Highly doubt T-Mobile is actually going to flaunt around a network refarm, entice unlocked phone owners (with their obvious focus on the iPhone), and then go ahead and give them slower speeds.
“We are going to make our network iPhone compatible. We’ve got over a million customers on the iPhone now,” my T-Mobile source said.
It felt that a fully iPhone compatible network, offering HSPA+ 42/84 and eventually LTE speeds coupled with T-Mobile's much more affordable voice, messaging and data plans would entice users to bring their off contract or unlocked iPhones over.
Also, directly from a T-Mobile press release - why would they advertise 70% faster speeds on their network versus AT&T?:In fact, we’re already starting to turn up 4G HSPA+ service in our 1900 MHz spectrum. With sites already live in cities like Seattle, Las Vegas, Washington DC and the New York metro area, don’t be surprised to hear reports of iPhone “speed sightings.” We expect to have these improvements deployed in a large number of markets later this year.
Our internal tests of unlocked iPhone 4S devices running over [u]4G (HSPA+) on our 1900 network[u] recorded on average 70% faster download speeds than iPhone 4S devices on AT&T’s network.

If they indeed bring the T-Mobile AWS bands to the new Lumias as they did with the pentaband 808 Pureview, then nobody will have to worry about which markets are fully refarmed when unlocked Lumias are available for purchase. (Unless T-Mobile picks up both phones anyway)

Please don't report posts unless they violate site rules. Anyway T-mobile will begin rolling out category 10 LTE over the AWS band in Q4 of this year and it will be complete complete and blanket their current HSPA+ AWS footprint by the end of 2013

Im not happy about this but you mite be?
The Samsung ATIV S has no LTE support!
HSPA＋ 42Mbps 850/900/1900/2100MHz
ATIV S - Samsung ATIV
LTE is next gen and if you are like me stuck in a 3 year plan you want the newest and greatest from now to 2015 eh?
