I noticed something odd. I have it sitting on my desk next to my verizon Phone. The Verizon phone is pegged at solid max signal. The Sprint phone will sit at max signal, then drop to no signal or 1 bar for no reason (it's not being moved or anything). Then suddenly rebound to full signal again. I have been watching this for a while now and it puzzles me. My Verizon phone does not do this. Has anyone noticed this before on Sprint's network. By the way I am on the 12th floor of the building and my window is less than 5 feet from me. It seems that there is a definate cycle to this bouncing, it happens every few minutes. It's just odd I tell ya.
