So, I've heard that there's supposed to be a 3G icon, and EDGE icon and a GPRS icon. I've never seen any of them. It says 3G when I'm connected though. My carrier only supports 3G so not having seen an EDGE icon is understandable. I've never seen the GPRS circle though, even though I turn on location services and use maps to find me and show me directions to where I'm going. How do I get it to appear?
