I got my Nokia 770 yesterday (bought it brand new from eBay) and everything worked fine for a few hours and I loved it. I even got the GPS Bluetooth Receiver and tested it out and it worked. After a few times of trying to run GAIM and having it freeze, it just froze and wouldn't turn off, so I unplugged the battery. Ever since then, I've been trying to turn it on, but all it gives me is a white screen for like 30 seconds and then it turns back off. I've tried it with the AC Power plugged in. I also left the battery removed all night yesterday, and it still isn't turning on. Any suggestions? If I reflash the memory, would it work or is this a hardware problem? How can I reflash it if I'm on a Windows PC? Thank you all for your help!

P.S. Nokia won't honor the warranty because I don't have a recepit
