    3G for Data. Is it not possible to separate the two? I know 3G voice calls are slightly clearer but i wouldn't mind trading for the battery life and when apps that connect to the internet need to use data they can just access 3G service

    I dunno it may sound crazy but i just thought of it when i saw the enable 3G pane

    EDGE (2G) and UMTS/HSDPA (3G) are data only.

    Voice is transmitted over GSM only.

    No. Very wrong. Read up and then come back.

    I have and I assume the OP is referring to how AT&T implements it.
    They do not run voice over their 2G EDGE network.
    They CAN, but they don't. It still falls back to GSM for voice calls.


    As for 3G, it does appear that AT&T has implemented simultaneous use of voice and data over 3G.
    It wasn't that way when they initially rolled it out.
    So I stand corrected on the 3G question.

    Can you stop saying that voice falls back to GSM? GSM isn't 2G or 3G, its just a type of cellular network, thats why people are laughing at your post. I suggest you reread and use the proper terms.

    Very wrong again. Do not take AT&T's web page as a fact. Actually do read up on what 2G, GSM, 3G, EDGE, GPRS, UMTS, HSPA, HSDPA, HSUPA and HSPA+ mean. Then and only then make a post commenting on it.

    I think it's a great idea. I don't notice any difference between 3G calls and EDGE calls. In fact, that last few 3G calls I have made had severe echo - I would hear what I said from 1 second ago on my own speaker. Data would be using 3G so you wouldn't miss any calls while using the data connection, which was my main concern with my original iPhone.

    when using 3g data, you can still receive phone calls. however, when using EDGE or GPRS, you can still only use one or other
