    guys , first of all i'm sorry if this is re-post ,
    but i do really need to know , for those who ever bought unbrand carrier ( direct from RIM ) for bold 9900,is the unbranded and unlocked bold 9900 can be used in 4g at&T network in united states ?

    and also how to know if this device can be worked in 4g network if that time the signal probably is in bad situation ? so is there any chance to know if the device is 4g capable or not by using other carrier ?

    and if from my old blackberry if i put the old sim card to the new bold 9900 , should i call the customer service from the carrier to do the sync or verify to the new phone that the sim card has been attached to or no need ?

    *note = i don't know if i should feel regret or not by buying this unbrand carrier bold 9900 or not , i'm just affraid this device won't work in 4g network , especially in tmobile or at&t network for the 4g signal . or after unlocked mode , the device can only be worked in EDGE network only , i'm screwed if that's happened .

    Call att reps or visit store and ask them.
    See what frequency is used by att for 14mbps relay
    And compare it with bb you are willing to buy.
    Ask to people selling this unlocked bb

    There are 2 different 9900 models.

    One with 3G bands 1, 2, 5 & 6 which will work fine on AT&T's 4G network, but not on TMO's.

    The other with 3G bands 1, 4 & 8 which will work fine on TMO's 4G network, but not on AT&T's.

    If you have the incorrect model, you'll only ever get EDGE on that network, never 3G/4G.

    To find out which 3G bands your phone has, go to Options > Device > About Device Versions. The bands are shown on the 4th line down.

    Even with the correct device for your chosen network, it still won't show 4G, just 3G. Only AT&T or TMO supplied phones will show 4G on their networks. You'll still be getting their '4G' speeds, but it will only show as 3G on an unlocked/unbranded phone.

    Can you buy a phone direct from BlackBerry? I don't think you can anymore, at least not a regular customer.

    Do you have a URL, or was it an employee or friends and family pricing?

    How do you get it serviced? Can you provide a link? The biggest problem with buying BlackBerrys from anybody but the carriers is you can't get them serviced. If this was possible there would be less threads on this forum about bricking phones; they would just get them fixed under warranty.

    Those specs are wrong... you have too many UMTS (3G) bands there.

    If it's an AT&T device you'll have UMTS bands 2100/1900/850/800 MHz

    If it's a TMO device you'll have UMTS bands 2100/1700/900 MHz

    When I was shopping for my BlackBerry, Best Buy Mobile had unbranded, unlocked Bolds and Curves. That was last year right before the 9900/9930 came out. Of course, ordering directly from RIM sounds better, cheaper. The prices at Best Buy were up there with the rest of them.

    Could it be some European device with different bands altogether?
