    You have the options of:
    1xRTT only
    EVDO Rev 0 only
    Hybrid Rev 0
    EVDO only
    Hybrid Rev A


    What does each of these mean, and what this the effect? It is defaulted at Hybrid Rev A. Im assuming this means it switches between 3G and 1x....

    They're pretty self-explanatory.


    1xRTT only - Defaults to only 1xRTT for both voice and data (Vision)
    EVDO Rev 0 only - Defaults to the previous version of EVDO (rev 0)for data, 1xRTT for voice
    Hybrid Rev 0 only - Switches between EVDO Rev 0 and 1xRTT as needed
    EVDO only - Will not use 1xRTT for data
    Hybrid Rev A - Switches between EVDO Rev A and 1xRTT as needed

    which one is best for your battery?

    for calls and just texting and web browsing of mobile sites ie.. m.precentral.net then 1xRTT only will work great and your battery will last about 30-40% longer. I do it all the time.

    If you are trying to view regular sites with heavy browsing. I would suggest leaving it the way it is. If you change it to the wrong thing you might not be able to get text messages.

    Messaging and voice run on 1xRTT, so you should be able to get them in any signal strength.

    Does anybody notice a time change whenever you switch between Hybrid Rev A and EVDO Only?
