Blue dot just means GPRS I believe...does anyone even remember this tech anymore? haha.
Blue dot = GPRS = General Packet Radio Service.
Wifi > 3G > EDGE > GPRS.
To be fair, the majority of the area I live in is only covered by GPRS, it's only really the cities that have EDGE (I still have a 2G iPhone). There are the occasional hotspots where the E will appear, but most of my area is GPRS only. It works fine for emails, IM+ and things like that, just don't try browsing on it![]()
