So CNET UK had a Nexus One whose screen mysteriously cracked and turned purple while merely charging on a desk. At Google's urging, they handed it over to HTC for further study. The results:
"Putting a phone in a tight pair of jeans and sitting down would usually cause the kind of damage," suggested our support guy. He agreed that it's possible that a small crack could spread over time, like a ding in a car window.
Words to live by, we suppose. But the question remains: What happened to Crave's Nexus One screen? Maybe it cracked under the weight of not knowing what's wrong with its multitouch? (Self-flagellation zinger there, folks.) [Crave.CNet.co.uk]
