Selling iPhone. How to list info correctly.
I'm selling my mom's iphone for her on eBay. I don't have a cell phone myself believe it or not so I'm not familiar with all the terminology. I look at some listings and I see stuff like GSM and **factory unlocked** and not sure what that is.
I know the phone is AT&T iPhone 4s white 16gb good condition (no scratches etc). Model on back is A1387. It's not on contract anymore. Does it mean I can say it is unlocked? Should I mention it is at&t.
What should I have in the title so it is both accurate and have the most people look at it.
Also should I use eBay or one of those sites for selling your phones like usell.
