My wife has an iPhone that was originally on Verizon that now has a Bad ESN, but that she is able to use on straight talk wireless. We brought it to a Verizon store and the manager told her to keep it and use it as an ipod as they didn't have any use for it and nothing came up on a database search of bad esn's. Out of curiousity I looked up iPhones selling on ebay and I was shocked to find that people pay big bucks even with the Bad ESN??? iPhone 6s Pluses sold for at least $500 and anywhere up to ~$800??? I am wondering why people buy them and pay so much? There is even a company that will give you a new version of the iphone you send them with a bad ESN for $100. I am thinking about sending my wife's iPhone 5 to them and getting back a new one for the $100 upgrade fee. Does anyone have any insight into this market? Thanks
