Customers who may be eligible to participate in the liquid sensor settlement class action involving certain iPhones and iPods are now receiving legal notices via email. A customer may be eligible if Apple denied warranty coverage because the company said a device had been damaged by liquid. The $53 million settlement fund will be split up amongst participating iPhone owners whose warranty claims were denied on or before Dec. 31, 2009, and iPod touch owners whose claims were denied on or before June 30, 2010. Oct. 21 is the deadline for filing a claim; affected users may receive between $105 and $300 per device, depending on the model and capacity. More details can be found on the settlement website.
