Cell phone developed a, um, "stain" on the main screen shaped like a football that obscured everything beneath it.
Took it to the Verizon store. Told them "Somebody sent me a kiss and I don't know how to erase it."
"Nope," said the clerk. "It's pressure damage. You'll need a new screen. About $80."
I found a screen replacement on Ebay for eight bucks. It came today.
Four of the tiniest screws I've ever seen, hidden under some equally tiny rubber plugs, held the case together. Opening the case, it was dirt obvious how to remove the old screen and replace it with the new.
'Phone works swell. I saved $75.00. All is good (except the debt limit which shall remain unnamed).
