Earlier this week Apple was sued, along with several app developers, for allegedly sending personal information to ad networks without the users' knowledge or consent. According to one industry lawyer, there could be more lawsuits on the way.

Speaking with InformationWeek on Wednesday, attorney Kevin Pomfret said the trend of consumers turning to the courts to protect their privacy is likely to continue. "I would not be surprise if there were more lawsuits," said Pomfret.

A lawyer who advises businesses on privacy issues, Pomfret said the law is "unclear" in this area.

Apple is no stranger to lawsuits over the iPhone. The company has been sued by big companies like Nokia, Motorola, and HTC. Apple has also been sued by individuals for not revealing that the battery was not user-replaceable and, in 2009, for MMS not being available on the iPhone.

This is also not the first time Apple has been named in a lawsuit against an app developer. In 2009, Tune Hunter sued music-finding service Shazam of patent infringement and named Apple, as well as a host of other companies, in its lawsuit.

The latest privacy lawsuit claims ad networks are able to trace an iPhone or iPad using the unique device identifier. The suit says the practice violates federal computer fraud and privacy laws.
