Is the "content store" everything that a user adds to "device memory"? For example, I cleared "content store" and the ringtone in "device memory" disappeared, and I restored "content store" and my ringtone came back. So, I'm wondering if "content store" backups up everything in device memory like photos, music, ringtones, etc.? If so, what is the upper limit for Mac (in MB), and what is the upper limit for PC (in MB)?
