For many iPhone and iPad owners, there is a need to synchronize device data to exchange contacts, library content, etc. There are two synchronization options: wireless and cable.
IPhone and iPad are synchronized automatically using iTunes. The biggest difficulty is that when you connect both devices, all the contacts, programs and media files they contain will be merged. If you try to delete one file, it will be erased from both devices at once.
To solve this problem, you need to create separate libraries for iPhone and iPad in iTunes. First, you need to connect one device, create a library for it, and then close the program. After that, you need to launch iTunes again while holding down Option for MAC or Shift for Windows. The program will open with a proposal to create a new library. You must agree, connect the second device and synchronize with it. After that, you can freely transfer files from one library to another.
