Not sure why it happens, but my behold would start up and then turn off, start up and then turn off, cycling over and over. I checked internet and no one had an answer. Finally tried this and it seemed to work. When the behold finally gets to the first screen (with widgets, phone, ph.book, web, and menu on the bottom of screen) I pushed on the touchscreen menu button. I only had a few seconds before it shuts down and restarts. The menu screen popped up and I went to the "settings" and then "reset settings". It asks for a password (I used 12345), and then confirm password. This will reset your phone, but you will also lose info. Or pics on your phone. Phone then did an automatic restart and my phone was back working. I was then able to restore my phonebook #'s because tmobile has an automatic phonebook backup. I hope this helps anyone with the same problem I had. Makes me angry that when I called tmobile they said no one has called with this issue yet I have found many people with the same problem. Obviously some type of glitch that seems to have an easy fix.
