I have a cingular treo 750w that is stuck in a multi colred screen that says serial across the center of it. I was doing nothing to the phohne, it was in its box, opend it up one day and turned it on and boom. I have put sims in it before using it to show people, and worked great. I have not hooked it to a computer or done any downloads to it.

I have searched for this issue, any help is appreciated
