On eBay all the time I see "iCloud locked" or "bad ESN". Is there any way to save these phones? I see them still selling for hundreds of dollars, I mean they must be of some value. I've been on the Android platform for years, I'm just coming back to Apple. I used to be into jailbreaking and hacking, I wasn't 1337 but I was adept. So are these phones junk, or can anyone offer links on tutorials how to repair?
