MobileDevice Library is used by [[iTunes]] to transfer data between iPhone and computer over both USB and WiFi connections.
   
===PC Windows : iTunesMobileDevice.dll===
+
=== Windows: iTunesMobileDevice.dll ===
  +
* Location: <code>C:\Program Files\Common Files\Apple\Mobile Device Support\iTunesMobileDevice.dll</code> (<code>Program Files (x86)</code> on 64-bit)
The DLL is written using Microsoft Visual C++ 8.0 DLL Method [2].
 
  +
* Supporting CoreFoundation.dll (used for CFStringRef, CFPropertyListRef management) is located in the same dir (when using [[iTunes]] prior 9.0).
  +
* For [[iTunes]] 9.0, the location of CoreFoundation.dll is stored in '''InstallDir''' registry value under '''HKLM\SOFTWARE\Apple Inc.\Apple Application Support''' registry key.
   
  +
=== Mac OS X: MobileDevice.framework ===
* Location : Location is stored in '''iTunesMobileDeviceDLL''' registry value under '''HKLM\SOFTWARE\Apple Inc.\Apple Mobile Device Support\Shared''' key. Usually - C:\Program Files\Common Files\Apple\Mobile Device Support\bin\iTunesMobileDevice.dll.
 
  +
* Location: /System/Library/PrivateFrameworks/MobileDevice.framework
  +
* Export command: <code>nm /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice</code>
   
  +
=== Library Interfaces ===
* Supporting CoreFoundation.dll (used for CFStringRef, CFPropertyListRef management) is located in the same dir (when using iTunes prior 9.0).
 
  +
* [http://www.libimobiledevice.org/ libimobiledevice] (provides the same functionality on GNU/Linux)
  +
* [https://github.com/imkira/mobiledevice mobiledevice] (command line utility for interacting with MobileDevice Framework)
  +
* [https://github.com/samdmarshall/SDMMobileDevice SDMMobileDevice] (OS X framework written in C that can be used interchangeably with Apple's private framework MobileDevice.framework)
  +
* [https://bitbucket.org/tristero/mobiledeviceaccess MobileDeviceAccess] (similar to above, but written in Objective-C)
  +
* [http://samdmarshall.com/media/MobileDevice.h MobileDevice.h] (old reverse engineered header for interfacing with MobileDevice library)
   
* For iTunes 9.0 location of CoreFoundation.dll is stored in '''InstallDir''' registry value under '''HKLM\SOFTWARE\Apple Inc.\Apple Application Support''' key, usually C:\Program Files\Common Files\Apple\Apple Application Support\. CoreFoundation.dll from Mobile Device Support\bin should not be used.
 
   
===Mac OSX : MobileDevice.framework===
 
   
  +
=== Private Functions ===
* Location : /System/Library/PrivateFrameworks/MobileDevice.framework
 
* Export command : "nm /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice"
 
   
  +
==== Obtaining address ====
===MobileDevice Header (mobiledevice.h)===
 
  +
In order to obtain the address of a usable private function in MobileDevice, you will have to be able to understand x86-64 assembly to reverse engineer it. These methods differ slightly based on platform due to how dynamically linked libraries handle position independent code.
   
Reverse engineered C header for MobileDevice Library.
+
=====Mac OS X (MobileDevice.framework)=====
  +
A private function is not marked as exported in the mach-o symbol table. This means it cannot be called by simply linking against the library. To call unexported functions, the mach-o symbol table must be stepped through manually to find the offset of a particular function call. Calls can be verified by checking against the offset of the name inside the name table.
   
  +
=====Windows (MobileDevice.dll)=====
<pre>
 
  +
Unlike OS X's dynamically linkable libraries, Windows dynamic libraries do not support position independent code in the same manner. A private function will not have its name in the exported symbol table, so in a debugger, like GDB, it will show up as part of another function. However, you will know that it is a separate function as a new stack frame is set up.

===AFC Connection===
 
...
 
 
===Locking the Device for Sync===
 
When iTunes sends a new song to the device, the device shows a "Sync in progress" screen and when complete, the Music app on the device re-reads the iTunesDB file so it picks up the new song.
 
 
To get this behaviour, first start the notification service:
 
<pre>SOCKET socket;
 
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);</pre>
 
 
Now we post a notificaton message to signal that we are going to start a sync:
 
<pre>AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncWillStart"), NULL);</pre>
 
 
Next we open the itunes lock file:
 
<pre>afc_file_ref lockref;
 
AFCFileRefOpen(conn, "/com.apple.itunes.lock_sync", 2, &lockref);</pre>
 
 
Now post a notification to say we are going to lock this file, and try and lock it.
 
If the AFCFileRefLock call fails, pause and repeat.
 
<pre>AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncLockRequest"), NULL);
 
mach_error_t error = AFCFileRefLock(conn, lockref);</pre>
 
 
When the file is successfully locked, post another notification, and stop the notification service.
 
<pre>AMDPostNotification(socket,CFSTR("com.apple.itunes-mobdev.syncDidStart"), NULL);
 
AMDShutdownNotificationProxy(socket);</pre>
 
 
Now the sync can proceed, so copy your files across and make the changes to the iTunesDB.
 
 
To release the lock, start the notification system again, unlock and close the lock file, and send a sync finished notification message:
 
 
<pre>AFCFileRefUnlock(conn, lockref);
 
AFCFileRefClose(conn, lockref);
 
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);
 
AMDPostNotification(socket, &CFSTR("com.apple.itunes-mobdev.syncDidFinish"), NULL);
 
AMDShutdownNotificationProxy(socket);</pre>
 
 
To handle "Slide to Cancel" and terminate sync when user slides cancel switch, use AMDObserveNotification to subscribe notifications about “com.apple.itunes-client.syncCancelRequest”. Then start listening for notifications (AMDListenForNotifications) until you get “AMDNotificationFaceplant”.
 
When notification got, you should unlock and close lock file handle (don’t sure if you need to post “syncDidFinish” to proxy, seems it doesn’t matter) and terminate sync gracefully.
 
The same notification is also got when you unplug your device, so you should always be ready for errors.
 
 
NOTE: You may find that starting the notification_proxy service once and once only at the start of your app and using the same socket in calls to AMDPostNotification works better. iTunes opens and closes the notification_proxy regularly, but it appears to be a bit flakey when you open/close it all the time.

===Private Functions===
 
 
====How to find address of privates functions in iTunesMobileDevice.dll or MobileDevice.framework====
 
 
In order to obtain the address of a usable private function in MobileDevice, you will have to be able to understand x86-64 assembly to reverse engineer it. A private function will not have its name exported in the mach-o symbol table, so in a debugger, like GDB, it will show up as part of another function. However, you will know that it is a separate function as a new stack frame is set up.
 
 
====Private Function Address List====
 
 
=====OSX.6 - iTunes 9.0.2(25)=====
 
<pre>unsigned int sendCommandToiBoot(struct am_recovery_device *rdev, CFStringRef command, int u);</pre>
 
Address is obtainable by adding 868(0x364) to the address of AMRecoveryDeviceGetProductType(), a public symbol that you can obtain via nlist() or dlsym().
 
Address: 0x1000245ea
 
 
Parameters
 
1. rdev - the device you wish to send the command to.
 
2. a CFStringRef of the command to send.
 
3. an integer, whose use is currently unknown, but should be set to 0 to work.
 
 
<pre>unsigned int sendFileToiDevice(struct am_recovery_device *rdev, CFStringRef filename);</pre>
 
Address is obtainable by adding 1763(0x6e3) to the address of AMRecoveryDeviceGetProductType(), a public symbol that you can obtain via nlist() or dlsym().
 
Address: 0x100024969
 
 
Parameters
 
1. rdev - the device you wish to send the file to.
 
2. a CFStringRef of the path to the file to send.
 
 
 
=====OSX.6 - iTunes 9.0.3(15)=====
 
<pre>unsigned int sendCommandToiBoot(struct am_recovery_device *rdev, CFStringRef command, int u);</pre>
 
Addresss: AMRecoveryDeviceGetProductType() + 0x37f(895); full offset: 0x2a0ed

  • Supporting CoreFoundation.dll (used for CFStringRef, CFPropertyListRef management) is located in the same dir (when using iTunes prior 9.0).
  • For iTunes 9.0, the location of CoreFoundation.dll is stored in InstallDir registry value under HKLM\SOFTWARE\Apple Inc.\Apple Application Support registry key.

Mac OS X: MobileDevice.framework

  • Location: /System/Library/PrivateFrameworks/MobileDevice.framework
  • Export command: nm /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice

Library Interfaces

  • libimobiledevice (provides the same functionality on GNU/Linux)
  • mobiledevice (command line utility for interacting with MobileDevice Framework)
  • SDMMobileDevice (OS X framework written in C that can be used interchangeably with Apple's private framework MobileDevice.framework)
  • MobileDeviceAccess (similar to above, but written in Objective-C)
  • MobileDevice.h (old reverse engineered header for interfacing with MobileDevice library)


Private Functions

Obtaining address

In order to obtain the address of a usable private function in MobileDevice, you will have to be able to understand x86-64 assembly to reverse engineer it. These methods differ slightly based on platform due to how dynamically linked libraries handle position independent code.

Mac OS X (MobileDevice.framework)

A private function is not marked as exported in the mach-o symbol table. This means it cannot be called by simply linking against the library. To call unexported functions, the mach-o symbol table must be stepped through manually to find the offset of a particular function call. Calls can be verified by checking against the offset of the name inside the name table.

Windows (MobileDevice.dll)

Unlike OS X's dynamically linkable libraries, Windows dynamic libraries do not support position independent code in the same manner. A private function will not have its name in the exported symbol table, so in a debugger, like GDB, it will show up as part of another function. However, you will know that it is a separate function as a new stack frame is set up.
