MobileDevice Library

MobileDevice Library is used by iTunes to transfer data between iPhone and computer over the USB connection.

PC Windows : iTunesMobileDevice.dll
The DLL is written using Microsoft Visual C++ 8.0 DLL Method [2].
 * Location: iTunesMobileDeviceDLL registry value under HKLM\SOFTWARE\Apple Inc.\Apple Mobile Device Support\Shared key.
 * 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 OSX : MobileDevice.framework

 * Location: /System/Library/PrivateFrameworks/MobileDevice.framework

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: SOCKET socket; AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);

Now we post a notificaton message to signal that we are going to start a sync: AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncWillStart"), NULL);

Next we open the itunes lock file: afc_file_ref lockref; AFCFileRefOpen(conn, "/com.apple.itunes.lock_sync", 2, &lockref);

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. AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncLockRequest"), NULL); mach_error_t error = AFCFileRefLock(conn, lockref);

When the file is successfully locked, post another notification, and stop the notification service. AMDPostNotification(socket,CFSTR("com.apple.itunes-mobdev.syncDidStart"), NULL); AMDShutdownNotificationProxy(socket);

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:

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);

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.

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.

OSX 10.6 - iTunes 9.0.2(25)
unsigned int sendCommandToiBoot(struct am_recovery_device *rdev, CFStringRef command, int u); Address is obtainable by adding 868(0x364) to the address of AMRecoveryDeviceGetProductType, a public symbol that you can obtain via nlist or dlsym. Address:

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.

unsigned int sendFileToiDevice(struct am_recovery_device *rdev, CFStringRef filename); Address is obtainable by adding 1763(0x6e3) to the address of AMRecoveryDeviceGetProductType, a public symbol that you can obtain via nlist or dlsym. Address:

Parameters
 * 1) rdev - the device you wish to send the file to.
 * 2) a CFStringRef of the path to the file to send.

OSX 10.6 - iTunes 9.0.3(15)
unsigned int sendCommandToiBoot(struct am_recovery_device *rdev, CFStringRef command, int u); Addresss:

unsigned int sendFileToiDevice(struct am_recovery_device *rdev, CFStringRef filename); Address:

As of now, Apple has decided to make these functions public with the following names:


 * _AMRecoveryModeDeviceSendFileToDevice
 * _AMRecoveryModeDeviceSendCommandToDevice
 * _AMRecoveryModeDeviceSendBlindCommandToDevice

The last of those returns no response from the device. One can only assume that the parameters to these functions are the same or similar to the private ones. They're not the exact same function though, as it appears that these functions call the previously private ones.
