We didn't change the image. It's an animated image, if all the frames don't load try reloading. May not always work when you have bad service.
As Grizz said, if he isn't dancing? Then it's your service/provider/speed. This is related to the problem earlier. Do you have any other carriers in your area? I would highly suggest looking into them. Where I am at, only Verizon works (And well, because there is a tower 1 mile away). That's it. No other carrier... My Brother in laws new iPhone is only an alarm clock when he visits and he has AT&T.
The other problem often is at my house. The dancing smiley thing was riding around at work. I had about 60% bars of 3g. Where I am there all chit. Verizon is best but one of the worst at my house.
You typically don't have bars of 3G... Usually you have service strength (voice and text) in bar form and beside it data speed (1x, 3G,4g).
