I have reformatted my Windows 7 PC. I did not back up the iTunes backups. I have Transferred Purchases, so my apps should now sync. If I attempt to sync, though my apps should be fine (due to Transferring Puurchases), I presume my Contacts, Messaging etc. data will be lost as my PC no longer has this information on it? Is this correct, or does that only apply to media and apps etc.?
