I just succesfully replaced the digitizer on an Aria that a friend gave me.
that I bought came straight out of San Antonio, Texas.
It works great. Just be sure to use the white plastic piece from the old one and you'll notice some black tape on the old one as well. Just below the 'home, back, settings and search icons, but on the inside. Place some black tape on the new one in the same areas. As far as the black sticky stuff goes, make sure your hands are clean and harvest it from the old one as well. It easily rolls out (like play dough) to be reused. No light bleed here.
On a side note. I passed on the Aria when it was first introduced, waited and got an Atrix. That said, I now think that I certainly could have got by with this great little phone. I am thoroughly impressed with the quickness of this little guy. Of course it has 2.3.4 CM7 on it and that has to help.
Thanks all for the info. This thread helped greatly.
