I had put up an iPhone 6 I was selling for my sister on Craigslist and last night it got stolen during a meet up with the thief. I had just paid $136 to fix the display. The phone had already been wiped before it got in the thief's hands anyway and was shown as offline on my sister'a iCloud account. I set it on lost mode but the phone hasn't come online yet. I'm wondering if the thief can still use it and if it's even worth filing a police report. I seriously doubt I get the phone back.
