My old iPhone and Captivate would show the network as something that would suggest it was connected to the MicroCell, such as "MicroCell." My wife's Veer does the same. However, my Focus only shows "3G," but I have five bars so I am confident that I am connected.
The questions are: (1) do any Windows Phones show "MicroCell?" and (2) am I the only one who sees this?
While I had the loaner Android, it didn't display the network name on the main screen. Rather, like yours, it said 5 bars of 3G. However, when I went into the notification screen, it did show the network name, which was "AT&T MicroCell".
The Android is not, of course, a Windows phone, but it is an(other) example of a phone that doesn't prominently display the network name.
