The "Other" category in the capacity meter keeps growing. I didn't even use it last night and this morning I synced it, the "Other" category grew from 400B to over 500MB. No app updates, no new files added, nothing. I got a few new emails but they are all text emails with no attachments. A few of them have a picture or two but not something 100MB+ in size. I thought maybe it was the cache from Safari or other apps so I rebooted it. Nothing. Any thoughts?
