Apple now claims an error in the iPhone 4 firmware is responsible for the dramatic drop in signal bars some have experienced when the device is held a certain way. An update for iOS 4 will be released in the coming weeks to address the problem, but in the meantime several lawsuits have been filed against Apple over the issue.

The most recent suit was filed Friday in the Northern District of California and accuses Apple of false advertising, breach of warranty, and unfair competition among other complaints. The plaintiff, Steve Tietze is seeking class action status for the case and contends that Apple is guilty of "misrepresenting and concealing material information in the marketing, advertising, sale, and servicing of its iPhone 4 - particularly as it relates to the quality of the mobile phone antenna and reception and related software."

When the iPhone 3GS came out, I preordered it from Best Buy. On the day before the launch, I got a call to schedule my appointment to pick it up.

The furor over Apple's iPhone 4 antenna design and its impacts on reception when held in the so-called "Death Grip" continue and here are the latest developments. First of all, don't expect AppleCare representatives to replace your iPhone 4 if you're experiencing the issue. Not only this, but Apple employees have been explicitly told not to offer owners free iPhone 4 Bumper cases.

A leaked document posted on BGR instructs Genius Bar employees to troubleshoot the problem, however if the antenna works fine when the iPhone 4 is resting flat on a table, then Apple considers the device to be properly operating. A software fix is not mentioned, and several solutions are to be suggested to the customer.

We've received emails from several iPhone customers, panicked over the possible loss of their yet-to-ship pre-ordered iPhone 4. These users have all received an email from Apple indicating that their pre-ordered iPhone 4, which was otherwise ready to ship, is being held by Apple based on instructions from AT&T. The letter instructs that Apple will attempt to reprocess the order daily for 7 days, at which time the order will be cancelled if the customer has not resolved the issue with AT&T.

The letter to customers reads:
