I've got a new laptop and have transferred my iTunes library from my old desktop to my new computer. I want to sync my iPhone with the new iTunes library, but I get the scary message that my phone is synced to my old computer, and all my data will be erased and replaced from the new library. What exactly will be erased? Is it just the music and other media files, or will I have to reinstall all my apps and other data as well? As a precaution, I've backed up my phone to iCloud. I'd hate to have to completely restore my phone, but if necessary I will. The instructions for this on the Apple Support site are not clear. Thanks in advance for any help/reassurance!
iPhone 4, running iOS 7.1.2
Computer is an Acer running Windows 8.1
Thanks!
