    us: add US Mobile (T-Mobile MVNO): mcc="310" mnc="260"
    
    This patch adds US Mobile (T-Mobile / Verizon MVNO) with the T-Mobile USA
    gsm APN settings. The type of "internet" is used to allow a single combined
    Cellular Data / MMS APN entry. Note that 310/260 is already specified in
    the T-Mobile provider entry as well as the SpeedTalk Mobile provider entry
    but these are the right network settings for US Mobile's T-Mobile network
    entry.
