    selecting and operating with the manually-selected non-home communication network in response to the user input;

    in response to regaining signal coverage from an out-of-coverage condition with the manually-selected non-home communication network while in the manual network selection mode, or in response to being powered-on from a power-off state while in the manual network selection mode, causing the following acts to be performed;

    if the non-home communication network is identified as being available, selecting and operating with the non-home communication network;

    if the non-home communication network is unavailable and the home communication network is also unavailable;

    displaying a list of available communication networks for a manual network selection procedure for manual network selection and operation with one of the available communication networks; and

    if the non-home communication network is unavailable but the home communication network is identified as being available;
