...and I can't access 3G despite having a strong four-to-five bar 3G signal on my previous phone. Carrier is T-Mobile USA. I've spoken to them and was advised to go to local store and pick up a new(er) SIM card, which I did. I then called back and some tech guy told me that this phone would NEVER run 3G on T-Mobile! I was aware of this problem on the iPhone, but, Acer? I simply don't believe it, having read a number of other complaints about fixing 3G problems that cropped up after downloading and installing 2.2. Here's what I've done: 1. downloaded, successfully installed 2.2 update from US website (despite phone's having come with 2.2 preinstalled) 2. done at least three factory resets 3. called T-Mobile about resetting after following their advice and getting a new, "3G-capable" SIM card (guess my previous one wasn't sufficient, although I never had a problem with 3G on the Moto Cliq the E replaced!) This is when the guy told me T-Mobile's 3G signal was unique and no phone, unlocked or otherwise, that wasn't supplied by T-Mobile would ever do 3G (except maybe some Chinese dual-SIM unit - which I don't understand!) SO, is that true? If not, any suggestions - other than spending $400-$550 for a new phone? Thanks, everyone!
