    It doesn't matter whether you are on TMO or AT&T, both use GSM, even for 3G.

    When qualcomm developed CDMA technology everyone was certain this was going to bell standard worldwide. What happened though is the carriers did not want to be tied to a chip manufacturer. CDMA is for more robust and advanced than GSM for good reason.

    Every cell phone provider whether it's CDMA or GSM use what are called Gateway or so called "Trunks". What this does is compress the amount of into a single pass through so the carriers can handle as many calls through one cell tower. This is where CDMA has a significant advantage. CDMA technology can compress many more cell phone signals than GSM can. Therefore, a company like vzw only has to use one cell tower where AT&T and TMO would need multiple ones for the same amount of cell signals.

    1 CDMA trunk can compress 1,000 lines into one without loosing the integrity of the call. GSM trunks can only handle 100.

    There a number of other advantages but just pointing out why CDMA is the more superior technology to GSM.

    That's great info J, never knew those facts. I love behind the scenes facts and stuff. One day I'd like to see a tower up close in person.

    Thanks for the explanation, pretty helpful. This alone may be the reason I switch, if only Storm 2 was already here.

    What 3G model is coming? I'm stilll seriously almost decided that I'm leaving to verizon. Too many instances where my coworker is anywhere in our building and has a strong connection where I have no connection what so ever. Its pretty bad for me now that I moved to an area where literally, I have no service and others on verizon have like 4 bars. I believe they have wide 3g coverage as well.

    If you are looking for better overall coverage I would go with vzw, there are areas where tmo rocks but you are not in one of them i believe el is
