Sanyo MM-5600

well i just got my 5600 today and was getting my phonebook and stuff set up,, while downloading a ringer, the phone said "post process, saving to phone" or sumthing like that, and then the phone screen just went blank and it shut down or something. it wont turn back on anymore, and the only way it will even try to start up is if u take the battery out and put it back in, but then after starting up for about 20 sec, it flashes a white screen and then blank again, doesnt respond at all. when i plug it in it doesnt charge.

I was jsut wondering if there was anyone else who had this problem, or if anyone had any idea what it could be.
