Clearly Gizmodo conspired with a guy who stole the phone. End of story.
Dude, you just committed slander per se!
The investigation is good news, because none of us has very good information on what actually happened. I.e., Giz says that the finder says that he called apple repeatedly and was blown off. Giz says that the finder said that he found Powell told them that he finder found Powell's contact information on the phone.
News reports, etc. concerning crimes are in my experience always misleading because they don't include all of the relevant information, and usually improperly characterize the information that they do have.
