After seeing someone ask for an explanation on the differences between each wireless coverage indicator, and a search that came up with no results, I copied this guide straight from the Blackberry Reference Guide that comes in the box with a new phone. (I apologize if there was a thread on this already and I just wasn't finding it.) I never knew the difference either, just that when I was on edge, I couldn't browse the web or use BBM. Now after reading this over I understand why. Hopefully this will help someone else out as well.
