    I got my Iphone at the weekend

    Brilliant apple store experience and the phone is perfect... :)

    To save battery its recomended to turn off 3G.

    I was wondering, how much difference this makes?

    At work for example, Ill listen to music for a cuple of hours in the morning, and on my dinner hour i'll do some light browsing and gaming.... and back to music in the afternoon.

    Is it worth turning off 3G while im listening to music, and turn it on just to browse the net?

    Does it really make much difference to the battery life?

    Its not a big deal or anything, just wondering.

    Loving the phone by the way :D

    Turning 3g and fetch off can increase battery life a fair bit. Can't say how much cos everyones usage is different. But tbh I do what you do without turning it off and finish the day with 30% battery.

    I would guestimate:

    3G turned on after 5 hours use and 15 hours unplugged: 5%

    Edge turned on, 3G turned off after 5 hours use and 15 hours unplugged: 40%

    Airplane Mode after 5 hours use and 15 hours unplugged: 70%
