in my point of view is obviously he still want to hang on it until he want to let go and send it to you.By that time, the phone may have some problem.When you do some transaction such as this must be dealt carefully..For you case i think you delay it too long and that fella take it as granted.Well good luck but dont let him push you too far..no point of getting the phone after few weeks.I mean the phone value is drop.
