Hello, I'm new to Android and enjoying it very much but I think this may be a dumb question so bear with me! In my instruction manual for my desire it lists three types of connection. EDGE, 3G and HSPA. One is denoted by 'E', one by '3G' and one by 'H'. I have only seen 'H' so far on my phone. Does this mean that it's the only type of connection available for me? Or does it mean it's the best connection available? And if that's the case what is the order for the best connection? Should I expect to see different letters at the top of the phone depending on the area I'm in and the reception I'm getting? Thanks in advance for any help and advice.
