Question around the 3G type icons. The manual lists two icons I have seen - a simple "G" with up/down arrows and "3G" with the arrows. It says one is GPRS and the other UMTS. For the uneducated like me, what's the difference please?
Also, whilst in a city centre today, I noticed that the "G" changed to an "H". Can't find that in the manual though. Any theories?
