I copied this from an earlier post on this site ... we followed these instructions in July and the phones worked fine with no bill surprises.
I've used an iPhone 3G and 4 at Desire. I use AT&T. The data charges incurred receiving and sending emails and using the Internet are what you want to avoid.
Here's what I do: On your phone, Go to General, Network, Turn Enable 3G OFF (to reduce battery drain) and Turn Cellular Data OFF (also turns off Data Roaming). Turning off Data Roaming will block emails, browsing and downloads.
Go to Mail, Go to Fetch New Data and Turn Push OFF. The phone should be set to Manually at the bottom. IF Push is normally OFF on your phone, and Fetch is used, set it to Manually, instead of Fetch every 15 minutes, for example.
Turn Wi-Fi “ONâ€
