UPS delivered mine today (UK) - had been pending since 13th December. Sent it in 6 weeks ago.
Looks like a refurb - in that it doesn't look like a brand new one to me??
4 hours after it arrived I got an e-mail from Apple saying it was being despatched - with a tracking number! (fail!)
Mine was despatched according to ups yesterday but I am apparently in a remote area so its scheduled for delivery tomorrow.
I found a website to put the serial in. It's a 6gen. Hopefully they are better than some reviews suggest. The more I read about it the more I wanted my original back.
