What is the difference between Wireless Short Message Search and WAP search?

And is it popular for Americans to search on their mobiles, pdas, blackberries?

"WAP: Wireless Application Protocol is an open international standard for applications that use wireless communication. Its principal application is to enable access to the internet from a mobile phone or PDA."

"Wireless Short Message Service (SMS) is a service available on most digital mobile phones (and other mobile devices, e.g. a Pocket PC, or occasionally even desktop computers) that permits the sending of short messages (also known as text messages, or more colloquially SMSes, texts or even txts) between mobile phones, other handheld devices and even landline telephones."

"According to the Mobile Data Association, June 2004 has seen a considerable increase of 42% in its recorded number of WAP pages viewed compared with the same period in 2003. This takes the total for the second quarter of 2004 to 4 billion."

"Since 2003 and 2004, WAP has made a stronger resurgence with the introduction of Wireless services (such as Vodafone Live!, T-Mobile T-Zones and other easily-accessible services). Operator revenues are generated by transfer of GPRS and UMTS data which is a different model to the Web, and usage is up. People are starting to use WAP and the early failures have been masked, as the real point of the system – access to wireless services and applications – has come to the forefront."

"Spin-off technologies, such as MMS (Multimedia Messaging Service) (picture messaging), a combination of WAP and SMS, have further driven the protocol. An enhanced appreciation of device diversity, supported by the concomitant changes to WAP content to be more device-specific rather than being aimed at a lowest common denominator, has allowed for the content presented to be more compelling and usable. As a result, the adoption rate of WAP technology is on the upswing."
