Hi. Umm I want to sell my old phone on Craigslist (or Amazon I guess), but I'm kinda apprehensive.
I want to sell an Android Verizon LG Ally (and an MP3 player but I'm not worried about that). I did a factory reset for the phone and took out my SD Card, and it is now unactivated. I've heard Android phones are bad at deleting all data and I wonder if my SD card data is still on the phone.

Also I'm not sure if the factory reset fixed the battery issue
Should I sell them on Craigslist or Amazon, is Amazon more safe? Please help.
