What is the difference between the communications board and the 4GB/8GB/16GB logic board on the ifixit store. for example: the following two products Product code: IF105-019-1 Product code: IF105-010-1 thanks,
The communications board controls the “phone” functionality (calls, text messages, etc). The logic board controls everything else. In other words, if the 1st gen iPhone could function with the communications board removed, it would have all the functionality of an iPod Touch.
