Nearly three years after the device first launched, GigaOm points us to a recently filed class action lawsuit that claims Apple’s iPhone 4 has a defective power button. The lawsuit claims that a defective flex cable typically causes the on/off switch to fail shortly after the device’s one year warranty has expired. It also claimsApple is aware of the problem, which is costing users around $149 to fix off of warranty.
Apple of course still sells the iPhone 4 through a number of carrier partners as its low end, $0 down iPhone option.
According to the lawsuit, “thousands of iPhone 4 users have suffered” from the issue that Apple allegedly knew existed before manufacturing and selling the device. The problem has never received a lot of mainstream media coverage or a response from Apple, but the lawsuit notes that a support forum on Apple’s website boasts over 800K views since first popping up in January 2011.
