Not sure which forum is appropriate as this is really a network comparison as experienced by the iPad device
A longish clip with no audio track or commentary but you'll get the idea
Comparison of using identical iPad 3Gs side-by-side on the Vodafone NZ network and Telecom XT. Shows high-speed browsing and download experience both in the city and outside the city.
[Moderator edit (MF): please watch the whole clip - it starts in an area where Vodafone 3G is 900 MHz, so obviously the iPad is operating on 2G. At three minutes it moves to Auckland CBD, where both networks are 3G]
