Here man... Do this....
Go here:

Download the ROM update. Install it.
Your done.
The new ROM is nice if the older owner hasnt done that already.
Once you do that come over to my site....
www.sskusers.com and flash yourself a custom ROM.
Also if you opt to go the hard reset way and you want to clear the music and all that off I would recomend doing the Both option on the hard reset. You stated you didint want the muisic and more than likely its in internal storage.
