Nope. Same dock connector cable.is it true they are thicker or some change was made to them?
Just get something like this:
http://www.amazon.com/Belkin-USB-Extension-Cable-10-Feet/dp/B00001ZWXA
The link shows a 10 foot cable, but they come in all sorts of lengths.
Apple sells an official extension cable.

I've used it since the iPad 1 without issue.
Total link is about 9 feet.
Not the cheapest, surely. That would be leaving the iPad closer to the mains socket so the standard cable workedThe simplest, cheapest and most flexible solution is a mains extension lead!
I use a 6' iPad/iPhone cable from Monoprice.
