I just updated from Froyo to Gingerbread (ver 3.3.3) on my Motorola DX. Really nice - fixes some bugs and has some nice new features. A question on one of the icons in the right side of the status bar. Can't figure out what it measns. It looks like 3 verticle wavy lines. When you turn the phone sideways, it looks like 3 capital "M's", but the normally vertical lines on the outside of the "M" are angled out. Does anyone know what this icon indicates?
