I had my Droid X since the release days. It constantly have dancing bars. It goes from 1 up to 4 and down to 3 or whatever random things it can do.
I live in the state of Oregon and this happen in Portland or any rural areas. One minute i have 5 bars and the other minute I have 1.
The wireless at home does the same. So between those two indicator its a dance!
It totally sucks! Any have the same problem? I used to be with ATT and planning to switch over again now.. or try the Droid Incredible.
