A lot of 5S's will be popping up on eBay now, so there could be a few bargains on there. My question is - how safe is it? I hear all the time about people buying phones, which either a) have a fault which isn't easily detectable without a decent amount of usage or b) the phone get blocked/blacklisted later due to the seller reporting it lost/stolen after its sold. Does eBay really cover you for things like this? If it does get locked, will I get a refund through PayPal or eBay?
