I want to move the syncing of my iPhone 4 from one computer to a new one, and don't want to lose any data (SMS, apps, etc.).
Anybody know how I can do this?
Yes, I did search the forums and Google.
1. The first thing you want to do is ensure you link your new computer's iTunes account to your current Apple ID. You can only have 5 authorized computers linked to an iTunes Account (unlimited devices).
2. After you do this to the new computer, I would then transfer all your media (songs, movies, podcasts, etc., to the new computer's iTunes library and link the newly transferred media). Search for best ways to do this, but with an external hard drive, you can easily transfer your iTunes Media folder over. THIS IS AN IMPORTANT STEP...GOOGLE HOW TO DO THIS!!! There are several ways, and depending on your needs, you'll have to decide which way is best.
3. After media is transferred over, connect your iPhone to the new computer. Select "manually manage music and videos" and also deselect Sync when connected to this computer. I do this so I can ensure I have all the syncing options I want before the computer starts the syncing process. After everything is done, you can go back and change these settings.
4. Now select your iPhone on the left panel of iTunes. Go through each tab (Summary, Info, Apps, etc.) and ensure you have it selected to sync how you want it to. This step will allow you to select certain areas where you want the data from the iPhone to overwrite the computers data for the first sync.
5. Next, Click File - Transfer Purchases from XXXXXXiPhone" This will take any purchased apps, etc. from your iPhone and add it to your new computer's iTunes library.
You should receive an error message that your iPhone is currently linked to a different iTunes library. By continuing, you'll erase all media on the phone and link to the current library. Since you've transferred your media already, this is okay...you will have to re-add the media back after the initial sync.
Now, all stuff you've purchased through iTunes/App Store should transfer to your new computer because it carries the same Apple ID. Once this is accomplished, you can sync (if it doesn't do so already with the transfer purchased items process).
BEFORE DOING ALL THIS, GET A GOOD SYNC WITH THE OLD COMPUTER JUST INCASE YOU NEED TO RESTORE THE IPHONE IF SOMETHING GOES ASTRAY!!!
I'm not certain if this guide will carry SMS/MMS over...if not, you can restore from the old computer to get back to where you started if needed.
Hope this helps.
