It may be interesting to keep a complete copy of all files on the iPhone, even if only for use with third-party tools, such as:

 save the voice messages received on the Visual Voicemail (Visual Voicemail);

 retrieve the full text - decode the traces in hides ;

 Etc ... It would be tempting to do with the tool "iPhone Folders" but he has an unfortunate tendency to crash when trying to transfer too many files ...

On the iPhone: - openssh package - the package rsync.

On the desktop:

 A client ssh - rsync tool.

On the PC, run the following command (in a directory to backup the iPhone):

rsync --delete -ave ssh root@xx.xx.xx.xx:/ .
where xx.xx.xx.xx is the IP address of the phone on WiFi equipment. You will then enter the password "root" by default alpine (unless you have mutually agreed the two machines by depositing the public key from the PC to the iPhone.

The first time, all files will be copied to the iPhone (which will take significant time). During subsequent runs, only the difference will be transferred (which also allows for easy error recovery).

Incidentally, it is also interesting (in a reverse Engeenering) to list files modified after a particular action on the phone, allowing better focus its research.

One can usefully add the option --progress to verify the success of synchronization, especially for large files.

Note: It is advisable to connect the iPhone to an external power supply to this, firstly because the internet is very energy-consuming, but also because it prevents the phone go into standby mode by stopping Login ...
