how to save the battery life?

[asouns]

GPS: do I need to turn gps off manually when Im not locating myself for the bettery saving? or it's automatically set to active when using the map app and turn off when not using?

3G: 3G only better for surfing speed or it also benefit for good phone voice?

thanks!

Turn both off when you aren't using them. 3G is only for faster web speeds, not so much voice quality.

Not true, 3G offers improved voice quality and the nice feature to be using the internet and still being able to receive calls.
