    For some that is the difference. GSM is the international standard and the most widely used with over 3 Billion connections worldwide.

    And lets not forget the convenience of SIM cards and unlocked devices...

    I've used both CDMA and GSM. The GSM call quality was much better.

    i'd have to disagree on that, CDMA has always been slightly higher quality. To ME the GSM advantage lies in
    a)Global dominance
    b)Sim cards make it so much easier to move contacts switch phones etc etc
    c)Simultaneous Voice and DATA where CDMA can do voice OR data but not both at once. (this is actually a UMTS/HSPA/WCDMA advantage but at the moment thats what the GSM carriers are implementing)
    d)due largely in part to GSM being the globally dominant technology, GSM seems to be the preffered outlet for the hottest newest devices, while CDMA GENERALLY gets a "remake" later on down the line.

    CDMA companies are GENERALLY more restrictive with their phone, ie verizons lockdown of everything, BREW games ringtones etc. Even though carriers like AT&T make an effort to get you to buy their stuff, they do not go as far to restrict devices as does verizon alltel sprint etc.

    bear in mind i said GENERALLY alot.

    O, ALSO, in areas with 3G its actually WCDMA now instead of gsm, still uses sim cards but the underlying technology i think is based on CDMA

    I'd have to disagree with you disagreeing. GSM has far better national coverage. There's places where GSM overpowers CDMA drastically, the only reason why there's some areas out there where its CDMA only and no GSM is because Verizon has monopolied with their landlines so AT&T or Tmobile can't go in and put cellular towers in those "few" areas.

    But I'm still confused as to why both AT&T and Tmobile work off GSM but when you put the 2 phones side by side, AT&T will ALWAYS have better signal strength and faster EDGE speeds. Weird.

    theres a difference between coverage and call quality...

    the difference im talking about is like listening to a cassette versus CD, maybe not so drastic but you get my point. I assume what you're saying is that GSM has better coverage, i'm neither agreeing nor disagreeing there. The point im makin is that the actual CALL quality, the sound you hear is slightly better with CDMA phones. On GSM calls i always hear a very faint static. Its not enough to turn me off to it, I love my GSM Blackberry and AT&T.

    I cant explain the T-Mobile vs AT&T thing but im sure there are similiar cases with sprint vs alltel vs verizon vs USCC. i think it has to do with tower strength, location, and condition.

    Yes but what good is a CD if the technology you have to listen to it doesn't work everywhere?

    Gsm all the way, as far as I have seen, the differences are very faint between them both, some have advantages over the other, but overall for BB I would take gsm, as for the device release time, curve was out last summer for gsm, and look it took the 9 months or so to come up with the same device for cdma, best part is 9000 is expected to be in june, while cdma curve is out within month difference

    i agree, i was just saying, CDMA does have its strengths, and I'll recognize them, but I still prefer GSM.

    Agreed, and thats part of the reason i prefer GSM over CDMA, and its self perpetuating. Since people who think like us go for GSM to get the newest phones, GSM remains dominant, and since GSM remains dominant, manufacturers prioritize GSM for new handsets and so on and so on.

    on the CDMA network, you are constantly connected on the network, good for gps, instant messaging and teathering. GSM on the other hand send out signal bursts to connect to the network, on the gsm, you wont be connected until you manually connect.
