I upgraded to 8.0.2 OTA shortly after it became available. I have itunes match enabled and only a couple of playlists actually downloaded on my phone. I was roaming in the US and started getting text messages from Bell in Canada saying I was at 100% of my roaming data (500MB) within 2 hours of being in the US. Went to cellular usage and saw it was all system services and media services. Figured out itunes match decided to sync my entire library for some reason. And over cellular. There didn't appear to be any way to stop it. I even disabled itunes match and deleted the music library from storage. It continued to download music!! Even after a reboot. I had to completely disable roaming data so that I don't have to take out a loan to pay my bill next month. This has already cost me $125 in roaming charges! Anyone seen anything like this?
