Excuse my ignorance but just trying to establish the correct setup for 3G and GPS on my SGS2.

Am I right in saying that the GPS button on the pull-down menu is purely for switching GPS on for Sat Nav etc and has no control over my 3G signal.....?

Also, under the network settings, what should I have ticked out of "Use packet data" and "Data roaming" for day-to-day web access etc when not in range of wireless.

I am familiar with Data roaming but unsure about packet data.

Also not sure about the Network mode........
