You'd think a cellphone's screen is too tiny for any, uh, "intimate" viewing.

Apparently not. The words "sex" and "porno" are among the most popular terms on mobile search engines, says a report from Crisp Wireless, a publisher of mobile phone websites for companies such as Time Warner and Paramount Pictures.

"Sex" and "Porno" were the eighth- and ninth-most-searched-for terms, according to Crisp's study of more than 14 million mobile Web users in the first quarter of 2008.
