I keep seeing phones for sale with the listing clearly stating it has a bad ESN and it's made me curious. Once a phone is stamped with a bad ESN for whatever reason, can it ever be re-flashed to have a "Good" ESN that a carrier, say Verizon for instance, will accept and allow the phone to be used on their network again? I understand that no one wants stolen phones out on the streets and that's one way to stop them from being used. I'm just curious as I see these phones being advertised on places like E-Bay or Craigslist for what look like high prices considering they're apparently useful only as an overpriced iPod type device with maybe WiFi services. Is a bad ESN phone only useful for parts now or is there some way to "rehabilitate" it and make it a phone again? (Hence the high prices some folks seem to want to pay for them) Just today's random question that's been bugging me.
