Apple iPhone 4 owners who did not collect a free bumper from Apple following the so-called "Antennagate" scandal can now collect their $15 settlement payment.

Users can file a claim for their cash payout at the iphone4settlement.com website, which just went live. According to the site, iPhone 4 owners have from now until Aug. 28 to file a claim.

The settlement is available to original iPhone 4 owners living in the U.S. who purchased the device on or before Feb. 17, 2012 and experienced antenna and reception issues. Those who already received a bumper or case from Apple are not eligible for the cash settlement.

Some 25 million owners of iPhone 4 smartphones make up the class in the recently settled "Antennagate" lawsuit. The settlement combined 18 individual lawsuits into one, and claimed Apple misrepresented itself by, "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."

The problem dates back to 2010 when Apple launched the iPhone 4. Shortly after the device hit the market, new iPhone 4 owners realized their signal quality dropped when they held their phone in a particular way. Namely, touching the outside rim of the phone where the two parts of the metal casing/antenna met would interfere with the signal, and cause enough signal degradation to ruin a call.
