I'm a new owner/user(about 3 weeks)and I'm very impressed with all of the functionality. Everything on the device worked seemlessly until I downloaded some wallpaper from this site. Otherwise I've only made some slight "cosmetic" changes. One of the main symptoms occurs when going in and out of my e-mail or when I try to go into voice-mail. It hangs while I'm trying to enter my password. Plus when I dial my e-mail it goes right into speaker......crazy behavior. Any way I can restore original setup config?, easily?
