Apple has issued a warning to European iPhone users telling them that the USB adapter they are using may pose a safety risk. Apple says that affected USB adapters were sold with the iPhone 3GS, 4, and 4S smartphones from October 2009 until September 2012.
All of the affected adapters have model A1300 on them. The adapters are being redesigned and all new adapters have model A1400 on them and the CE symbol is outlined in gray. Apple is replacing the adapters for users at no cost.
Apple says that these affected adapters have the potential to overheat and “pose a safety risk.” What Apple means is that they might catch fire. The replacement program is underway now. Users who want to replace their adapters can request a replacement here.
