I thought my phone was rebooting itself like it's done several times in the past but when I tried to turn it on all I get is a solid blue screen. I googled this and found out that this is what they call the Blue Screen Of Death?? My phone isn't even a year old!!

The above link gives information and solutions for the 928.
