I would argue with your "claiming it's a phone". Under that rationale, everyone using Internet Explorer is committing fraud as soon as someone decides to price-discriminate based on it, since it claims to be Mozilla [1]. User agents are totally discretionary. It's like the color of your laptop. [1] http://www.useragentstring.com/pages/Internet%20Explorer/ http://www.useragentstring.com/pages/Internet%20Explorer/

> everyone using Internet Explorer is committing fraud No - there's no financial gain from using IE. He has manipulated his computer to inform web servers that his device is a mobile device. I'm not aware of any desktop browsers which use mobile device user agent strings during normal operation. Whether it is discretionary or not is irrelevant, the point is that he's deviated significantly from normal behaviour, deliberately, without any legitimate reason (e.g. he wasn't at the time say, testing a mobile site), in fact with only the intent to defraud. Ultimately, user agent strings are not a brilliant way to create a legally binding contract - it would be much smarter to have the contract amended based on the user-string to include "I confirm that my device is a laptop", and make this click-through.
