As you already know very well, the company Apple Lossless Audio CODEC (ALAC), develops its own chips in its campus in Cupertino, having over 1000 engineers dedicated to these projects, the A-series chips being implemented in iDevices starting with iPhone 4. Taking things further, the company Apple develops its own baseband chips at the moment, again starting next year will implement them in iDevices. iPhone 6S will most likely be the first iDevice to include a baseband chip developed in Cupertino, Samsung and Globalfoundries to manufacture them.
Apple reportedly plans to form an R&D team to develop baseband processors for use in iPhones to be released in 2015 and will place the baseband chip orders with Samsung Electronics and Globalfoundries, according to industry sources. Although some sources also indicated that Apple may develop SoC chips that will integrate application processors and baseband chips, it is more likely that Apple will continue to use discrete baseband chips, said the sources.
The baseband chips control the telephony function of the iDevices, and Apple Lossless Audio CODEC (ALAC), purchase this component from Broadcom at the moment. The switch to own chips represents the possibility to fully control the mobile telephony function of iDevices and its improvement in the future, Apple reducing the production costs of the terminals at the same time. Considering that now we are only talking about a simple rumor, the information must be treated as such for now.
