Synced iPhone to wrong Mac?

I synced my iPhone to my iMac no problem. I then tried to sync it with my MacBook when it started telling me that if I did that I'd be removing all the content from the iPhone. So my question is did I sync it to the wrong computer in my house? I want it synced to my MacBook b/c it's the computer that has all my music on it.

The iPhone can only be synced to one Mac. If you wanted it to be synced to the MacBook, why did you sync it to the iMac?

So yes, what it's telling you is true. When you sync the iPhone to the MacBook, it will erase whatever's on it now and re-sync from the MacBook's iTunes library, iPhoto library, Address Book, etc.

If your MacBook and iMac use the same iTunes account, I would say this is pretty much a non-issue, since you'll be able to get back all your purchased apps/music/video, Game Center info, etc.

What about things like Notes, Calendar, preferences, etc.? Is there a Time Machine-like app for backing up an iPhone?

I moved from syncing to my old Windows laptop to syncing from a Mac Mini. It worked fine. The only thing I needed to redo was tweaking which app appeared on which home screen on the phone. No content or preferences were lost.

Low risk approach:

• Back-up the iphone on your iMac
• Sync it to your MacBook
• If it doesn't work properly, restore the iPhone on your iMac

Simples!
