What does the "D" mean under 3G in my slide down bar? I'm leaning towards signal strength/type of signal, but I cant find a definitive answer anywhere. Any help greatly appreciated. On a side note, the app Quick Settings says "No APN Configured" under the G/3G tab, I know this relates to MMS and internet access but I can't find any info on the subject (ie. how to "configure" my APN) Thanks guys/gals... FYI - I can send and receive pictures just fine.
