    I doubt it!
    Any proof?
    I read an article from an expert said that 2100 and 1700/2100 are different, even if it has 2100, the freq. actually can be different.
    So iPhone 3G won't work on T-mobile 3G.
    It has 2100 doesn't mean that it works on a 2100. It could be a different 2100. Because it is not exactly 2100. It could be 2090 or 2110.

    i called t-mobile support asking them this specific question. they said that if you're subscribed to their t-mobile internet (19.99 package), you get 3g if it's available. i asked them specifically that if the iphone 3g were unlocked, would it be able to support the t-mobile 3g network, and they said that there is nothing at t-mobile's end preventing the iphone 3g from accessing the internet (except for the frequency thing, that is).

    from what i've heard on hackintosh and other places, t-mobile's 3g network is 1700 MHz for uploads, and 2100 MHz for downloads. i'm not too sure, and someone will have to confirm this. it may or may not work on the iphone 3g.

    either way, i have an iphone 3g just waiting to be used on t-mobile. hope t-mobile's 3g works!

    It has to be a 6-band chip. Think about it. Apple made this phone before they got all these carriers to cary it. Not knowing what networks would use what frequency. It would be a pretty boob move if apple built the phone to only support AT&Ts 3G then push the phone to networks all around the world not knowing what frequency they use.

    Making the phone multi-band would have gave apple a little more leverage when negotiating contracts with carriers. Making it one freq. would mean only a hand full of carriers could support the phone. Carriers could use that to there advantage. You want to sell your phone in this country we are your only option get it. ^-band gives apple the upper hand. This is what we want or we take it to your competitor.

    I find it really hard to believe that all the networks carrying the iphone 3G use only that one frequency.

    the iphone is OFFESHALY listed as a tri band both 2G and 3G
    so actuialy apple dose have some leeway

    and apple has been knowen to use inferior stuff

    just look at the new macs thay still use 802.11 G
    no N support out of the box

    so it really wouldent supprise me if thay
    use a triband or quad band chip with prats disabled
    but i too hope apple did the smart thing and used a 6 band chip just waiting to be tapped ( hacked ) by the dev team

    actuly we should ask the dev team how many bands the 3Gs chip supports
    thay should know given thay have been working on it for 4 months

    and forgive us our bandwidth as we forgive those
    who refresh against us
    And lead us not into yiphone
    but deliver us from zibri

    tool of all...

    Where did you get this information?
    In contrast, Apple usually uses state of art technology.
    Like LED LCD, small-package Intel CPU, multi-touch screen, DisplayPort, etc.
    Even my 2-year-old MBP has 802.11n chip.
    I don't have a new MB/MBP but I don't think they are going backward and withdraw 802.11n support; their web site also has big 802.11n signs.
    I do believe what Jimbean2 said.
    It probably has 6-band chip in there.
    But the firmware may not support it (yet).
    The last time I heard T-Mobile US is the only carrier in the world using 1700MHz, so I guess there is no urgency for them to enable it now.

    Its a 6-band chip.

    http://www.infineon.com/dgdl/X-GOLD6...1957c66fee3850

    Notice Key Benefits.

    Quadband EDGE / triband HSDPA

    Its also a multimedia chip. Application processor. I dont think its bring used for that but someone could hack it to give the phone a little more power.

    wrong! it says in that pdf that it is a triband HSDPA. it is either one of the triband, or the other: 850/1900/2100 or 850/1700/2100 MHz


    this is what i found on another website:


    UMTS / HSDPA devices operate in UMTS frequency bands 850/1900/2100 or 850/1700/2100 MHz:
    2100 (downlink) / 1900 (uplink) for Europe and Asia (usually referred simply as W-CDMA 2100)
    1900 / 850 (independently, for both the uplink and downlink) for America (e.g. AT&T)
    2100 (downlink) / 1700 (uplink) for America (e.g. T-Mobile)
    850 for Australia (Telstra NextG)
    UMTS / HSDPA / HSUPA is a further evolution.
    Note that being UMTS / HSDPA / HSUPA tri band doesn't mean that phone is a GSM / GPRS / EDGE tri band. An HSUPA tri band might not be a GSM at all. However nearly all HSDPA or HSUPA tri band are EDGE quad band too.
    A 3G Quad band offers more coverage.

    Devices
    Some UMTS / HSDPA 850/1900/2100 tri band are already available:
    Apple - iPhone 3G

    this is what i found on another website:
    The PDF says Dual-mode HSDPA what does that mean? If it is only 850/1900/2100 could we download only? No uploads? They both use 2100 for downloads.

    Edit: T-mobile uses 850 for uplink in some places so it could work on t-mobile.

    I don't think so.
    You need to send packets back (i.e. upload) when you download.
    Let's hope what Flicks said is true.
    Nobody else tried T-Mobile 3G on unlocked iPhone 3G (either officially or via SIM solution)?
    I wish I could find someone with a 3G account.
    I guess dual mode means GSM/WCDMA.

    the no n support come from the latest keynote video
    out of the box the new MPs dont have n cards

    but thay are an upgrade option

    and its listed on both AT&Ts site and apples
    that the iphone is a tri band phone

    most if not all internashanial phones have quad band support
    and the only one who really can tell us how many bands the 3Gs chip supports would be the dev team
