I bought my bionic on tuesday and have yet to see 4G at the top.is there something I have to turn on.I have yet to see a difference from my Droid X except for a couple extra icons.I put my Bionic next to a DroidX and opened a web browser and there just about the same.Now as far as the look and feel there is a small difference.We were told the display was 4.5 inches.No change.
