My iPhone is currently synced to my old computer, a PC. We just recently bought an iMac, and I've already transferred my music from my PC to my new iMac and am using the same iTunes account. If I plug my phone into our new iMac (even though it is synced to the PC), and press "sync", will I lose everything because its syncing to a new computer?? Or what will happen when i press sync on the new iMac?
