CommManager symbols?
 

What are these items on the CommManager?
To the left on the bottom is PushEmail. So what is the item circled in green?
And the one in red? Something to do with volume? Transmitting?
Of course, the ones I know get titles when pressed.

Green - Cellular data connection
Red - Infrared

I don't seem to be able to toggle the data connection button. Is that correct or is that a function (or non-function) of the custom 3.5ROM?

For Sprint, we're talking EVDO, correct?

you can use it when you are connected to data to disconnect, but not to actually connect. thats how i turn off data sometimes...you can also hold the end.handup button for 3 sec and that will disconnect too :)
