Analog and Digital? Strange...

[UTSAFTW]

I only once have run into this before and hit digital without thinking much of it. I just ran into it again while talking to my brother-in-law. I have no clue how I accessed it or whether it is relevant or not.




Unfortunately when I slid the keyboard open, it disappeared. Anybody else run into this before?

Edit: I only brought this up since I know that Ev-DO based chipsets should only be Digital (Ev-DO and 1xRTT), but not analog so this surprised me.
