Ever wonder what all those icons mean at the top of your Windows Phone screen? Look no further at Microsoft has gone ahead and detailed all of 'em for you.  Things like roaming, DO (for EvDO, CMDA's 3G standard) and a few others may be a little obscure, so it's nice to have a key.

Sure, for many of us who've been around smartphones, the support article at Microsoft seems like a big ol' "duh" but there are more non-smartphone users in the world than ones with, so be kind.

Even more icons and descriptions can be found here on Microsof'ts support page.
