    How does the switching between WiFi and GSM data transfer works on an iPhone ?

    When there's a WiFi network available, will the iPhone switch automatically to this network for e.g. checking for email or surfing the web ? And vice versa ?

    So if I entered the GPRS data settings in my phone, will it use them whenever there's no open WiFi network around ? Can this be customized with with profiles ?

    At the moment, I'm not sure when my iPhone switches to GSM data transfer or WiFi. Of course, this is all about money...

    It will automatically switch to wifi networks the iPhone has joined in the past.
    If there are wifi networks in range but the iPhone never joined before, there will be a pop menu where you can choose the network you want to join.

    It basically remembers the SSID of networks it has joined and will join them again if available. Otherwise it will ask to join.

    And yes it will switch back to EDGE if no wifi.
