Do yourself a favor and read this article.

Apple never made and never sold a 3rd generation 8GB iPod Touch.
Do yourself and the rest of us a favor and get over it.
There is no such thing.
The article above says it all.
What is the number on the back of your iPod Touch...
A1288 which is a 2nd generation iPod Touch
The link you point to does NOT say it is a 3rd generation model.
