    Can someone tell me why the sky rocket has a different radio from the Vivid and also which would be the better lte radio?

    Vivid:

    Network
    2G Network GSM 850, 900, 1800, 1900 MHz
    3G Network HSDPA 850, 1900, 2100 MHz
    4G Network LTE 850 MHz

    Its an error. At&t and Verizon both operate solely within the 700Mhz spectrum currently. Once At&t completes its acquisition of T-Mobile it will convert their 1700MHz spectrum to LTE as well.

    Ok thanks that's what I thought as well.

    Actually that's incorrect. AT&T already has AWS spectrum they're reserving for LTE deployment.

    Has anyone seen a review that discusses the speeds they are seeing on the LTE network? Also I'm curious to see if the ATT LTE phones have better battery life than the Verizon ones.

    AT&T claims to have a better switching technology for 3G to 4G than Verizon and says it gives them better battery life. I think that's how I remember reading it. Don't remember where I saw the article though.

    Please tell me what exactly in my reply was "Incorrect".

    Fact: At&t "Currently" only uses 700MHz for their LTE, which is what I said.

    Fact: Once T-Mobile is purchased, At&t plans to use their 1700MHz spectrum for LTE.

    If you would like to call someone "Incorrect" You should elaborate.

    I read the CNet article as well but wanted to understand is it true or just an ATT Exec blowing smoke. Thanks for the reply.

    Incorrect. Let me repeat it one more time...
    AT&T already owns sufficient amount of AWS (1700Mhz if you don't know what AWS is) spectrum where their LTE is already being tested. They have their specific blocks of 1700Mhz ready to deploy LTE on.

    Disclaimer FYI: 1700Mhz is 100Mhz of spectrum not a single band. There are multiple bands auctioned on that 1700Mhz spectrum. AT&T has 10-40Mhz of their AWS band ready to be deployed for LTE, T-Mobile has completely different blocks of that 100Mhz chunk. The LTE devices on AT&T network are not compatible with T-Mobile AWS band at all. All AT&T's LTE devices have both 700Mhz band 17 and AWS band 4 antennas in them, and their LTE modems are both 700Mhz and 1700Mhz ready.
    Please get your facts straight.

    Then why did At&t spend all that money a few years ago to buy up 700 MHz spectrum at the FCC auction a few years ago after the TV's went digital?

    The 700 MHz signal is much stronger (or decays less rapidly), needs fewer towers and penentrates buildings better. I think they are touting their LTE network as 700 MHz as is Verizon's. Correct? Did not see a AWS 1700 band listed on the specs for this phone.

    If you think that "Fact: Once T-Mobile is purchased, At&t plans to use their 1700MHz spectrum for LTE" is an incorrect statement, then you are ignorant. I'm not nor was I ever disputing that At&t already owns AWS of its own. I never even brought it up. I simply said that it will use T-Mobiles AWS for its LTE plans. Either you have a reading comprehension problem, or you're completely ignorant. Either way you shouldn't be posting on here.

    And who are you to tell me not to post here?
    I'm trying to educate you and correct your completely wrong posts so people don't get the wrong information.
    Here it is once again: T-Mobile's AWS has nothing to do with AT&T's current LTE devices. Even if the merger goes through, it will take years for AT&T to free up T-Mobile's AWS band and migrate all the users to other bands.
    And please do us a favor and calm your rage. You sound really pissed.

    Here is the LTE testing portion of Samsung's Skyrocket FCC filling: https://fjallfoss.fcc.gov/eas/GetApp...tml?id=1532866
    If you look at HTC Jetstream, or any other AT&T branded LTE device, they all have 700Mhz and 1700Mhz band.
    Looks like AT&T may supplement their markets that don't have 20Mhz of 700Mhz spectrum (Chicago only has 10Mhz) with 5x5Mhz on their 1700Mhz band. That way they'll be able to evenly compete with Verizon's 20Mhz nation wide market license.

    I see. Thanks for the info. So not all AT&T LTE will be the same Freqs or speed? Interesting.

    You're welcome! Basically they have two bands (4 and 17) where they will be deploying LTE since they don't have 20Mhz of 700Mhz nationwide like Verizon. Verizon won upper block nationwide license and that gave them huge advantage since they can just deploy 20Mhz on a single 700Mhz band coast to coast.
    But deploying 700Mhz and 1700Mhz for LTE shouldn't be a big issue as the users should get similar user experience, except their maximum theoretical LTE speeds wouldn't be 73.6mbps (like on 20Mhz), they will be 39mbps (using 10Mhz).
    Aggregation or channel bonding won't be available until LTE-Advanced or 2013.

    Assuming the ATT+TMO merger goes through and ATT actually does start using some of TMO band for LTE, will the Skyrocket be able to work on all ATT and also all TMO LTE bands?
    Or will it only be able to work on some and not others?

    That's a great question. The LTE baseband chipsets are programmable, so since all the internal components (filters, antenna, amps) are already tuned to 1700Mhz, it shouldn't be a problem for AT&T to make the existing devices operational on T-Moible's AWS bands.
    However, from the moment the merger goes through, add at least 2-3years until those bands are ready for AT&T to deploy LTE. By then, you'll probably have way more pimped out smartphone

    To sum it all up, It's an awesome phone, I'm getting it even though NYC isn't LTE ready as of now! And I'm buying it full price. That's how much I like the phone.
    *EDIT* great news for NYC: http://mashable.com/2011/11/04/att-l...new-york-city/
    I'm ready to lock myself to unlimited LTE data plan

    I'm debating doing this as well. I would also be paing full price. I actually live in the DC area so it would be sweet. But being full price, I just may wait a couple weeks and see if there is any word on the Nexus. Hell i may buy it on launch, then sell it if the Nexus comes. Damn is there an Android rehab? I'm addicted.

    buying it at Costco you have 90 days return policy. But Nexus on AT&T will be HSPA+ only, LTE exclusivity in the U.S. is reserved to Verizon. You could technically buy an International unlocked version of Nexus, it'll work just fine on AT&T. It's coming out in the U.K. on the 17th.
