I agree...sometimes the finders keepers thing applies, but...when it comes to blackberrys...a persons life could be in there. And if they are like me, they don't backup their devices as much as they should. So if you were to wipe it...they would lose everything. I think the best thing is to let the carrier know. Either way, it is probably unusable by you, it is probably reported lost/stolen and cannot be used again anyway other than its owner.
Device: Sprint 8330 Curve - Crimson
