There are four masts in my area - a 2g mast, an HDSPA mast and two 3g masts. Unfortunately my SGS2 prefers connecting to the 2g mast and this is very slow for a Data Network Connection - internet connection is near useless through this mast. I have two questions:- 1) can I set the phone so that it bypasses the 2g mast and connects to one of the others. 2) which will provide the fastest internet, HDSPA or 3g, and how do I ensure I connect to the fastest. Answers to these two questions gratefully received.
