I wish i had have been sensible and post here too, when my hd2 touch screen stopped responding. Mine would be on and off. One day it would work and then the next it wouldn't. Like all my old electronics i have which i have replaced with more modern technology, i pulled it apart (with no care for the internals) just for the fun of seeing what was on the inside.
I miss that phone. I now use a Motorola Razr HD. I hate it. Actually, since the good ol' Hd2 days, i've grown to dislike most Android phones. They're too big, lacking physical buttons and Android apps have become overloaded with adds. sigh i miss my hd2.
