iphone 4 "How do i limit my phone to 3G only?"

[yhang23]

My network settings are these : Enable 3G : ON
Enable Cellular Data : ON

sometimes when i surf the net, i get the 3G logo or the blue circle logo beside the name of my phone carrier. What does the blue circle logo mean? i am suspecting that it states that my phone is using GPRS to surf the net. Is that so?

if so, how do i limit my phone to using of 3G only? GPRS bills are gonna KILL ME! =(

I don't think there is any way to limit it. It automatically switches between 3G,Edge,and roam. Only option is to turn off the 3G.

Why would GPRS be more expensive than the faster 3G??

There is no way, the phone will automatically switch between the best signals available.
