Doesn't the iPhone 5 work on AT&T's LTE?

The iPhone 5 for AT&T has LTE. You can't bring that phone to Verizon or Sprint and have it work on Verizon's or Sprint's LTE.

I'm no antenna expert, but antennas are capable of receiving more than one frequency, and can get "tuned" by the receiver for specifics. Since frequency is a wavelength, and antenna design is partially based on the wavelength of the frequency you're trying to receive, it seems that making an interoperable LTE phone for Verizon and AT&T would be pretty simple.
They did it for GSM and CDMA (in the iphone 4S and Qualcomm S4 chips). The issue is deciding to dedicate the TX/RX channels to those frequencies.
It's certainly a solvable problem. I never said it wasn't, however the phones that exist today simply cannot do this. Someday it may happen, but given the history of carriers in the USA, the only interoperable networks+handsets for LTE will likely be T-Mo and AT&T.
Back to the reason I think we won't see LTE in this phone...
T-Mobile still has most of its HSPA+ deployed on AWS spectrum. AT&T has LTE deployed on this spectrum.
Adding LTE on the Nexus (alongside GSM and HSPA+) would be really messy.
The situation will be improving as T-Mo migrates HSPA+ to the PCS spectrum (mimicking the AT&T network) and lights up LTE on AWS (also mimicking AT&T).
Once this reaches a critical mass, we'll likely see an unlocked Play Store Nexus with LTE.

I still don't get what all the fuss is about lte. I've gotten speeds as high as 12 megs on hspa+, that's the same as my home network. And with limited data plans about the only real benefit is bragging rights with speed test screen shots. I have an lte phone, and I chose it over the regular gs2,and in hindsight I regret it. Battery life is horrendous over lte for no noticeable benefits

I get up to 3mbps w/ HSPA and 40mbps w/ LTE. There is a HUGE difference in my area.
+1 this. There is NO reason Google shouldn't be able to do this. No one is saying that Google needs to have ONE phone to sell to everybody to use LTE on ANYONE'S network. Just sell multiple devices on the Play Store and each one works with LTE on the network you want it to work on. Just like Apple does it. Just like Samsung did with the S3.
