I have had the galaxy nexus GSM on T-Mobile for about a week now and I have noticed the data isn?t much faster than my HTC sensation 4G it replaced. I see H connection most of the time but my speed tests have only been between 1.5 to 3.5 down. When I go in to setting/about my connection always shows HSDPA it has never shown HSPA /+ even though I am in a HSPA + area(san Diego). I was wondering if I need a new sim or if I need to call T-Mobile to have them change something on my account. I am currently using my sim from my HTC sensation 4g. thanks for any help in advance
