    For data, the iPhone uses the following priority....

    Wi-Fi
    3G
    EDGE
    GPRS

    So if you are on a Wi-Fi connection, the iPhone will only use that connection for data, until it is out of range, or it can no longer get any response through the Wi-Fi connection. It then drops to 3G. If there is no 3G coverage, it drops to EDGE. If no edge, the GPRS. If no GPRS, then no data will function.
