So, lets do it the right way and flash it across their small screen 
with meaningful information and not assumptions that are unlikely to be true.

With a decent UI design you can get that information without 
button-pushing or knob twisting. Frankly, if I had to choose between 
displaying the SSID and displaying a character or two of real 
information the SSID would be gone. Displaying an icon is much more 
likely to convey reliable information.

The problem is, that it isn't. It's a really lousy filter because you 
have no idea whether the sender is using the same filter you are 
using. How many times have we seen people asking why a thunderstorm 
is driving down the road because they're using an outdated symbol set?

This is the crux of the whole issue. It absolutely DOES impact those 
mobile users because if they are making incorrect assumptions about 
what those SSIDs mean they have wrong information which is arguably 
worse than no information.

So, if it is a growing category lets do it right and display the 
information we already have rather than putting bandages on that 
likely will lead to wrong assumptions about  what those mobile users 
are receiving!
