Earlier today, Nowhereelse.fr highlighted new part photos posted by Japanese vendor Moumantai showing what is claimed to be from the iPhone 5S or perhaps Apple's lower-cost iPhone. The part corresponds to an iPhone 5 part attached to the top end of the main logic board, but does contain some layout differences.
The corresponding iPhone 5 part houses a low noise amplifier from Skyworks that is involved in cellular connectivity. The part shown in the new photos also contains an antenna connector, which appears to correspond to one located nearby on the main logic board in the iPhone 5. That iPhone 5 connector is believed (but not confirmed) to be for the device's Wi-Fi antenna.
Minor parts for the next-generation iPhone have been leaking over the last several months, although identification of the devices associated with those parts has been made more difficult by rumors that Apple is looking to introduce both an iPhone 5S and a lower-cost iPhone later this year. In past years, Apple's strategy has been to release just one new model while keeping previous models available at lower price points.
