The personal injury law firm that sued Facebook and Zynga is now gunning for Apple

Here come the lawyers.

Less than a week after the release of the iPhone 4 -- and the first complaints of reception problems -- a Sacramento-based law firm has begun soliciting clients for a possible class-action lawsuit against Apple (AAPL).

"If you recently purchased the new iPhone and have experienced poor reception quality, dropped calls and weak signals," reads the advertisement posted by Kershaw Cutter & Ratinoff, "we would like to hear from you."

The firm is best known in Silicon Valley for suing Facebook and Zynga over the way Farmville and Mafia Wars players get dinged for alleged unauthorized charges. But according to its website, the firm's main specialties are medical malpractice, insurance bad faith, whistleblower lawsuits, dangerous drugs, defective medical devices and nursing home abuse.

Apple has acknowledged user complaints of signal attenuation when the new iPhones are held in certain ways, and Steve Jobs has suggested in a private e-mail that a solution may be in the works.
