How much is a stolen phone worth to sell?

Answer 1

Almost as much as you bought it for. If you wipe everything on the phone, delete all the messages, all the contacts, and all the pictures(as long as the phone is still in good condition) a stolen phone can be sold for as much as it was paid for when bought.

Often times, people will just use a ransom to the person they stole the phone from, for twice as much as it's worth.
