U.K. iPhone Ad Banned Due to 'Misleading Claims'
The television ad which can be viewed online claims that "all the parts of the internet are on the iPhone." The complaints about the ad pointed out that the iPhone does not support Flash or Java which may be required for some websites. The Advertising Standards Authority concluded that "the ad gave a misleading impression of the internet capabilities of the iPhone".
Apple responded by saying that the purpose of the ad was to point the iPhone's ability to access standard websites and that it could not ensure compatibility with "every third-party technology in the marketplace".
