I've had my Verizon iPhone 4S for a few days now, and it seems to switch from 3G to the blue circle (which means the slower 1xRTT) a lot. It can happen when I'm just sitting at my desk at work, so it's not like I'm moving around. Also, the last couple days I've held the iPhone in my hand during my 20 minute drive to work and it usually says 3G, but today during the entire drive to work it showed the blue circle. Makes me think something is wrong with the phone, and not Verizon. Why would locations that show 3G one day drop to the blue circle the next day? Or why would it switch from 3G to the blue circle when I'm just sitting at my desk? Anyone else have this problem? EDIT: Hmm, one thing I've noticed a couple times now is that if my phone is showing the blue circle and then goes to the lock screen, and then I unlock it, it will show 3G again. Weird.
