Paypal pretty much always sides with the purchaser. Even if you do receive the phone, there's nothing stopping you stating that you never received it (unless shipped by recorded/signed for), opening a paypal dispute and them then returning your money...
Problem is, if the seller empties their account and disappears.. paypal won't get you your money back.
