What to do about eBay buyers you know aren't genuine?

I just listed an iPhone 5 on eBay (an unwanted upgrade) brand new and everything, hoping for a quick sale. Within 3 minutes of the listing, someone had purchased it. Great, I thought, iPhones must really be in demand. But when I look at the buyer's profile, they have 0 feedback and all their details seem fake (unless the guy has a really strange name). I'm pretty certain this buyer is a faker and isn't going to pay up anytime soon and tbh I'm worried about getting scammed. I have to wait 4 days for him not to pay before I can take it up with eBay. Is there anything I can do in the mean time? I've already sent him a payment invoice with a message attached.

Don't send the phone until you have the payment in hand.

Firstly you should set your preferences not to sell to anyone with less than 3 feedback etc; Go to Ebay preferences and select seller preferences.
Contact the buyer and tell him not to pay because you do not sell to zero feedback members.
You are not obligated to sell to him and can refund a pay pal payment or return a cheque recorded delivery.
Stick to your guns as zero ebay members are highly suspect!

And don't click onto any URL that are sent within an email confirming payment as these are always PHISING SCAM.
Aces EBAY AND PAYPAl the way you normally do

Do not reply to any messages except through Ebay as fraudster get you email address WHEN YOU CLICK ONTO THE FAKE URL {Cut and paste} and messages after from fraudster avoid ebay

Via ebay messaging I hope

You are only SCAMMED if you send the phone and are NOT paid, which happens if you speed up or ignore Ebay / paypal
