cell text messages

About a year ago, Joe Shields got an unwanted text message on his cell phone promoting an astrology Web site, and Wednesday Shields learned he'll get up to $150 for his trouble.

Shields was among several cell phone customers participating in a class-action lawsuit intended to strangle mobile phone spam before it can spread as it has on the Internet.
Mobile phone carriers walk a fine line concerning cell phone solicitations or ads.

While they hate having customers annoyed by unwanted messages, they also are looking for ways to boost revenue through advertising that their customers buy into.
