Fresh on the heels of the Senate interrogation of Carrier IQ, the law firm of Hagens Berman has just filed a class action lawsuit on behalf of four smartphone users against Carrier IQ, HTC, and Samsung. It's unclear how much in damages the lawsuit is demanding, but initial estimates are in the hundreds of millions of dollars.

The suit alleges that all three companies have violated the Federal Wiretap Act and California's Unfair Business Practice Act (it was filed in the U.S. District Court for the Northern District of California), and the official press release specifically mentions Trevor Eckhart's research into the matter (go, Trevor!). Additionally, Hagens Berman is interested in discussing this matter with other smartphone users who use devices running Carrier IQ software.

The full press release can be found at the link below, as well as contact information for the law firm in case you want to get involved.

Update: There are now reports of at least two more lawsuits popping up, this time in Delaware and New Jersey, and now including Sprint, AT&T, and T-Mobile.
