    After years of waiting for T-Mobile USA to update their systems... They've finally done it. New York was launch on May 2, 2008. There were many expeculations that they would only relase 3G Voice, but not 3G Data; what's the point right? Well, finally they released 3G with Voice and Data. What's Even better news is that it seemed that they would use a 1700 MHz frequency and that would suck... but I spoke with a "special Tech. Team" department and I was told the lauched it using 2100 MHz... what does it matter? who cares? well, for one, T-Mobile Phones suck (service and price plans are the BEST)... i've used PDA's from Cingular (Now AT&T) from the beggining; like Treo 650, 680, 750, and Centro... but now just upgraded from iPhone to the new iPhone 3G and one of the frequencies in the iPhone 3G is 2100 MHz. The person I spoke with added that T-Mobile should complete the upgrade to 3G by the end of this year; AWESOME!!!

    what? where in that article does it say they are using the 2100 MHz frequency?

    it's true t-mobile has tested, and in certain areas use 2100 MHz but 98% of the very small t-mobile 3g network is still 700 MHz, meaning your awesome 3g iphone is not using the 3g network reguardless of what your "special team" told you

    1. the article link i added on the original Thread was the one showing that T-Mobile lauched... there are many more articles.

    2. T-Mobile owns a 1700 Mhz and 2100 Mhz of UMTS/HSDPA Network and NOT 700 like you said... just check the FCC auction that they won and purchased.

    3. The Rep told me that for the USA market, it was impossible for them to build on the 1700 MHz and that's why they only went with the 2100 MHz

    4. Don't forget that it was not to lond ago that T-Mobile was actually "Leasing" or "Borrowing" Cingular's Network towers... which means their system is built off of the same system that AT&T's was built from (since AT&T was ONLY TDMA before they merged with Cingular)... I hope you were aware that both T-Mobile and AT&T built their systems off of Cingular's.

    here's one more link to wreck your brain (much older than the first link i posted):

    I think the rest is fine, but what people are looking for is an independent verification, preferably in print, of this claim.

    i can defanitely understand that... i used to be a cell. ph distributor and i know a few people hear and there, but of course, something in print is definately the way to go. i'm not trying to prove anything here; just wanted to share my bit of knowledge and share my JOY to know the my money will be VERY WELL SPENT on the iPhone 3G (I was willing to accept that it would only work on the EGPRS [EDGE] Network), but this news gave me an incredible JOY!!!

    AT&T is using 850 and 1900 (UMTS band II/V). T-Mobile USA is using 1700 and 2100 (UMTS band IV).

    The iPhone 3G supports "UMTS/HSDPA (850, 1900, 2100 MHz)"

    Only one T-Mobile USA frequency is supported by the iPhone 3G.

    On T-Mobile's USA network, the 1700 MHz part is used for the uplink while the 2100 MHz part of the spectrum is used for the downlink (network to mobile).
    Since the iPhone does not support the 1700 band, it will still not work with T-Mobile.

    Here's a good read from March last year on the topic.

    the 700 was a typo, supposed to be 1700, my bad

    the iphone supports the t-mobile downlink, but not it's uplink

    what you don't seem to be understanding is that cell phone networks are a full duplex network, meaning it needs to have both channels open at any time so information can flow both ways simultaneously. i don't know how a phone would react if it could not connect 100% to the network (aka only it's downlink)

    but logically speaking, it will not work. if it does work, i don't see it working very well at all

    well maybe T-Mobile will switch their frequencies in consideration to the high volume of ppl and new customers who want to use iPhone 3Gs with T-Mobile service...

    However: The iPhone 3G supports the voice/call spectrums that T-Mobile provides, and
    the iPhone will automatically use the Edge or GPRS signals of T-Mobile that it finds once it fails to establish connections on 3G

    *all in all, i am stressing that the phone will work for calls, and data will fully work on both T-Mobile's GPRS and Edge networks.!.

    But the question is how do we get the out of the AT&T contract that were already in. I guess we have to pay the Early Cancellation Fee which is costly. Any other ideas?

    Well, that's a question, but the question is still who can validate yehudah72's claim. Per all the publicly available data to date, the systems will not be compatible, as rjohnstone and others have said above. So if yehudah72 is correct, it's actually a substantial departure from what's been out there to date. To be honest, it sounds very difficult to believe. Spectrum is sold by auction. T-Mobile USA doesn't have spectrum on the bands the iPhone supports, and the iPhone doesn't support the band that T-Mobile does have.

    So the question is really still how this could be possible.

    a lot of bad info in this thread.

    the T-Mobile 3G network is not compatible with the iphone 3G AT ALL. T-Mobile uses 1700mhz downlink and 2100mhz for uplink but it is a different range 2100mhz than what is used in Europe and on the iphone 3G.

    dont listen to what some retarded T-Mobile rep says they have no idea what they are talking about or are lying to you. EDGE is the best you will get on T-Mobile with the iphone 3G.

    So will you still get an iPhone for use on T Mobile even if the data is not working?

    Does lack of a data plan keep visual voice mail from working?

    :mad:will the same thing happen with the BlackBerry Bold????? :eek:

    ALL if not MOST 3G phones wont support the 1700 MHz

    Maybe T-Mobile USA is planning to get many exclusive phones?

    Please comment

    There won't be any switching going on. Cell phone companies pay tens to hundreds of millions of dollars when the FCC auctions these frequencies off.

    No. EDGE will work fine, but UMTS will not. Maybe the next version of the iPhone will include support for 850/1700/1900/2100 UMTS frequencies.

    HTC is releasing a Tilt specifically for T-Mobile to coincide with T-Mo's 3G rollout. It includes the 1700mhz band so it's definite, definite that a 3G iPhone will not be getting 3G on T-Mo.

    As far as I know, T-Mobile US'es 3G network is NOT compatible with any other carriers'.

    The iPhone 3G will NOT work with T-Mo's 3G network. Phone calls and data on Edge will work.

    If 3G speeds are important to you and your iPhone, don't try using it on T-Mo.

    As neither the OP nor anyone else has provided any substantive evidence to believe that there's been a change from what we know about T-Mo's 3G network in the US that would allow the iPhone to work on it, I'm closing this thread...
