Strange Screen Indicator Droid x 2.3???????

[Tdm123456]

I am running the gingerbread pre release for the droid x and am not rooted. I am noticing a strange indicator in the middle of the 3g symbol and the bluetooth symbol on the indicator bar. It looks like 5 vertical waves pressedpressed together. I have searched everywhere and can't figure this out?... can someone please help me? Thank you!!!!!

That is the "Vibrate" Mode icon...click the Volume Up button and it will disappear until you put the phone back into Vibrate Mode...
