I have a 8GB 2G iPhone, firmware 2.2; using iTunes 8.1

I tried using MediaMonkey to load some music onto my iPhone. (apparently not a good move) Afterward, iTunes gave me the "cannot read contents..." message. I figure I messed something up, so tried deleting the /Media/itunes_control folder; iTunes recognized the phone, and allowed a restore from backup. But, after the backup, got the same message. When I open the ipod on the phone, it shows no music, videos, nothing.

Went ahead and did a restore/jailbreak/unlock, then restored the backup once again. Same thing. Tried this a couple of times, still no music on the phone, itunes still won't recognize.

Is there a way to reformat, then restore? The rest of the phone works fine, but iTunes won't read the phone.
