I dont have a android phone yet. I dont use my current phone for many outgoing calls and never go online through 3G. I want an android phone mainly for using google mail and calender but would like to know if it can be set to ONLY update through wifi and never through 3g? I would of course buy a sim-free phone(probably the HTC bravo)and then continue using pay as you go and not a contract. Thank you. Hope this post makes sense!
