ESNs and Asurion

[knexx]

If I lost a phone and claimed it through Asurion, do they block the ESN on all carriers? I found the phone recently, it was under a metal brace under the seat in my car, and the battery was dead, so I couldn't see it or hear it! But I want to give it to my friend who has MetroPCS, will the phone work on that carrier? My phone was a Sprint phone. I'd hate to have to throw it away(recycle it).
