I have been travelling into London working the past couple of weeks and noticed that on certain parts of journeys on hammersmith and city line my S2(GT-I9100) switches from "H" to "4G" and back again.
I had noticed quicker downloading of browser pages at around the same time...
What does the 4G really mean? Surely the i9100 is only hspa/3g?
