I just ended my two day trial with the Droid Incredible 2 due to outrageously bad signal/reception and went back to the 9650. Where the 9650 had two bars, the Incredible has NONE!...no signal at all. Even in my house, the 9650 has all five bars... the incredible would have one or two bars. I never knew that there could be such a difference.
So yes, I'm wondering about the signal/reception and sound quality of the new 9900 series.
