Motorola adopts Google approach.....

Motorola is developing software which scans SMS messages on the users handset to then deliver ' relevant ' advertising, using a combination of key words from the text and also your GPS location.

The article in the Times goes on to give examples of a user texting the word ' hungry ' to then be sent adverts for restaurants in the local area.

Recent studies from Dynamic Logic for the Hilton’s Hampton hotel chain showed a positive increase in the Hotels brand awareness by advertising on weather.com’s WAP (Wireless Application Protocol) site, demonstrating there is indeed a market for relevant mobile advertising content.

All sounds interesting working in a similar fashion to Google Mail, therefore the same concerns have to be raised over privacy and relevance.
