I've got a RAZR Maxx that I love but have an issue... I live in a 3G area, on the way to work I hit a 4G area and the phone picks it up no problems. I do have a problem when 4G drops, the phone doesn't drop back to 3G - it drops completely and I get a message there is no internet connectivity. Is this normal? I've changed my network settings to use CDMA only and I don't lose network connection.
