Just got my wife the iPhone 4 and she's been setting up her contacts. We use the same iTunes acct, but use separate computers (hers is on windows, mine my MBP). If I try to sync her contacts to her machine in iTunes, it warns me it will erase what I've been syncing on my MBP with my phone. I have sync turned off on her phone at the moment. By backing up her phone, does that save her contacts as she has them in the phone? Do I have to sync them to ensure they won't be lost if I have to restore the phone? Thanks.
