Just got off the phone with AppleCare. They acknowledge that this is not a problem with my iPhone itself, and that it's likely a problem with iTunes Match. Restoring won't work since that won't affect your iTunes Match account. I suggest that everyone start calling AppleCare about this, and start making some noise. Apple doesn't really watch these discussions much, so talking about it here, although helpful to each other, does not actually address the problem with Apple. The tech that I just talked to is escalating the issue up to the group who handles iTunes Match. We need to give them some more examples.
Here's the run down of what I told AppleCare:
- The problem ONLY happens when I'm on a cellular network. In my case, it's AT&T.
- It never happens on my iPad (wifi only)
- It never happens on my Mac mini
- My MacBook Pro, which is the master system with all of my iTunes content is also unaffected.
One other thing that is worth mentioning is that I use iCloud as well, but with a different ID that transitioned over from .Mac to Mobile Me to iCloud. This started as a paid .Mac account, and is now a paid iCloud account. I use iCloud for synching my contacts, bookmarks, iWork files, my notes, reminders, and iPhone backups. It's possible that the iCloud account is conflicting with my Apple ID used for iTunes and Mac app store purchases, which is also used with iTunes Match. One problem here is that long time Apple customers like myself who started out with a .Mac account before the iTunes store launched still have the old account in place. It was logical to simply keep the .Mac/Mobile Me account and move it to iCloud as a paid account. I never thought about the possibility that this could be a problem moving forward. Apple sees this as two Apple IDs, even though I've never used the iCloud ID in association with any purchases that I've made on the iTunes store, or the Mac app store. Why this would only happen when I'm on a cellular network is a mystery to me. I'm wondering if any Verizon or Sprint customers have this problem. If so, please speak up. My data plan is a 4GB package that is part of the Mobile Shared plan.
