Don't bitcoins need 6 confirmation in order to get fully confirmed?
If there is any possibility of using a bank account then you should abandon the idea of Paypal completely. Even if you can find somewhere or someone nuts enough to sell to you you'll be losing 20-50% to cover their risk. It's overwhelmingly toxic in this scenario.
You'd get more money with him buying a bunch of phones on Ebay and you selling them on here for BTC for a sizeable loss.
Where the risk is gone - you selling Bitcoin and being paid out in Paypal by a reputable company like Coinbase - so are the premiums.
