Apple ipod

How I can know if I am using GPRS or Wi-Fi on my iPhone?

And people with disabilities bring new data "services location "," allow "3G" data roaming. "configure my Wi-Fi connection to my own network but when I check my mailbox, the icon changes to Wi-Fi GPRS icon. If GPRS, how I can disable?

Maybe what we need; http://www.modaco.com/content/pocket-pc-software/246171/new-free-utility/ Hope that helps.
