I was using Pandora at work for 8 solid hours on my phone for weeks. Then last week I kept dropping into 1x during the day. Only between 8-5 would it do this. Full signal bar normally have full 3g. At first it was 3pm on to 5 that it would be 1x then it was all day until it hit 5pm on the dot. I just left it alone and quit listening to pandora at all and it hasn't happened since. Is Virgin Mobile knocking me to 1x so I won't use Pandora?
