Hi...I am new to owning a smartphone and also have a 3g connection. I just bought the D3 a couple month ago and have recently noticed that the 3g signal notification will fluctuate from full 3g bars to 1x low connection. It does not stay constant and the signal is constantly bouncing back and forth between the two. Is this something that is normal? I thought paying for a data plan meant that I would always be connected to their 3g network and not lose signal. I'm sorry if I'm misunderstanding but as I said I am completely new to all of this.
