Remember the kerfuffle over Apple's "3G" television ad for the iPhone? In it the company demonstrates the speed of the iPhone on AT&T's 3G network. As it turns out the ad was edited to exaggerate the speed of the iPhone 3G and the speed shown is impossible to replicate in the real world.
The television commercial was cleverly debunked in this YouTube video and Apple eventually added a tiny on-screen disclaimer that says "network performance will vary by location."
Today the commercial was banned in the UK by the Advertising Standards Authority (ASA) which received 17 complaints that the ad was misleading for "exaggerating the speed of the iPhone 3G."
