Subscribed to iTunes match yesterday and had my iPhone 4 and iPad downloading tracks directly to the devices from iTunes, nice. Today, i decided to go upgrade to a 64GB iPhone 4S - got home, backed up, restored, everything working ok. But no music. so i enabled iTunes Match only to find out that you can no longer sync - you have to literally invoke the download of every track you want on it if you have not already synced your device. That could take a while with 5000 tracks Figured out that if you turn off iTunes Match from the device, then plug it back into your pc/mac it will enable the sync options again so you can do a one time sync to get everything you want on the device. Phew. Hope this helps anyone in the same predicament.
