Mobile SEO - Separate URL's

[siva s]

We maintain two different URLs — one for mobile users and another for
desktop users , make sure you inform Google explicitly when to serve which
version. Google does not recommend separate URLs because it can detect
automatically that your mobile pages are different from your desktop pages.

I don't agree with you creating all separate mobile urls. Yeah a small extensions such as 'abc.com' to 'm.abc.com' can be done but otherwise its not necessary.
