Try to reset the phone back to default settings.For technical support contact your service provider directly.

...Help? I didn't drop it or anything, I had sent a text and then tried to go delete my inbox as usual, and it restarts. I didn't think much of it, so I went to go do it again, and it restarted again. And now it wont quick restarting. Is there an online manual for the Motorola i669? Or tech support? Anything will help, thank you.
