The short story is that you are not going to get them... I ordered 5 R4i from 0shippingzone on Dec 22 and receive them by Jan 8, also order the 5 micro sd from another china vendor and receive them a day earlier so all this slowdowns that I keep hearing over and over are just lame excuses. But the bad news is not over, if you pay with PayPal, you can't even make a dispute to get a refund because is been more than 45 days since you make the payment. I'm really sorry for you, I also got ripped off, I ordered the same 5 R4i's from ShopTemp with expedite shipping, got them in a week or so and the 5 where faulty and when I make the claim they told me that they were closed. I was "lucky" that I was on time to open a dispute... I haven't received my money back thou, so we will see. :0/
I really hope you get them somehow, good luck bro!
