Remember all of the issues that the iPhone 3G suffered after users updated to iOS 4.0? Phones became incredibly slow and buggy, and in some cases unusable. And, since it's not possible to downgrade your OS (at least, not in a way Apple recognizes), 3G users were stuck with slow and difficult-to-use phones. Now a new lawsuit alleges that Apple knew updating an iPhone 3G would cause problems.

The San Diego woman who filed the suit is hoping to have it elevated to class action status, which would mean that a large number of plaintiffs (i.e. all 3G users who updated to iOS 4) are eligible to potentially benefit from the case.

According to the complaint:

"Even though Apple has actual knowledge of thousands of complaints from iPhone 3G/3GS consumers, Apple does not allow for those same users/consumers of third generation devices to download and re-install earlier and optimized iOS3.x operating system without resorting to 'hacker' tactics that will void Apple warranties and violate iPhone user agreements."

The plaintiff goes on to say that Apple's intentions were malicious because they essentially forced 3G users who ran the update to purchase a new phone. There's no mention of the latest iOS update, which attempted to fix most major issues caused by updating an iPhone 3G.
