How To Stop iTunes Automatically Syncing Your iPhone, iPod or iPad

iTunes Auto Sync Slowing You Down?

If you’re wondering how you can stop iTunes from automatically kicking off the sync + backup + update process when you plug your iOS device in then look no further.

By holding down the Shift + Control keys (Windows) or Command + Option keys (Mac) and then plugging your iPad, iPhone or iPod into your USB port you will tell iTunes not to sync!

If you happen to miss it and sync kicks off anyway, either slide the unlock slider on your device or hit the eject symbol in iTunes and your device will gracefully stop syncing and disconnect.

This was tested using both an iPad 2 and an iPhone 3GS on iTunes 10.2 (Mac).

How to Find Your iPhone’s Unique Identifier (UDID)

What is the UDID?

Each iPhone or iPod Touch has a Unique Device Identifier (UDID),
which is a sequence of 40 letters and numbers that is specific to your
device. It’s like a serial number but much harder to guess. It
will look something like this:
2b6f0cc904d137be2e1730235f5664094b831186.

Why do we need the UDID?

Your iPhone can only install programs that are approved by Apple.
Applications in the App Store have been approved by Apple for general
distribution, but beta customers get to try the app before it’s in the
store. We register your UDID with Apple so they can approve our
application especially for your iPhone.

How do I get my UDID?

You can copy/paste your UDID from iTunes or email it directly from
your device by using a free app from the App Store.

Verifying iTunes video conversion and video syncing using sample QuickTime files

Verifying video conversion in iTunes

iTunes includes the capability to convert some movies into a format that can be played on your iPhone, iPad, iPod, or Apple TV that supports video playback. To verify that videos you convert using this feature play correctly, follow the steps below:

1. When the conversion is complete, iTunes will create a copy of your movie in your iTunes library. There will be two movies listed with the same name. The sample_iTunes file with a kind of "MPEG-4 video file" is compatible with your device.
   
2. Download this QuickTime sample movie: sample_iTunes.mov (right-click or Control-click this link and save it to your desktop). If you are using Internet Explorer, choose Save Target As from the shortcut menu. If you are using Safari, choose Download Linked File from the shortcut menu. Note: If the movie starts to play in a browser window, click Back and try again. (Make sure you hold the Control key down while clicking if you don't have a right button on your mouse).
   
3. Open iTunes and add the sample movie "sample_iTunes.mov" to your Library. Note: The file may also appear as simply "sample_iTunes." To add the movie, open iTunes and choose Add to Library from the File menu.
   
4. Locate and select the "sample_iTunes" file in iTunes.
5. From the Advanced menu, choose Create iPod or iPhone Version or Create iPad or Apple TV version. While converting, you will notice an item named "Converting..." appear in the list on the left.
   The "Converting..." item disappears after the conversion is over.
