White screen after boot, only status bar visible

Question

A few days ago, I had a message on my HP Veer 4G that a restart was required. I'm assuming something had been updated. After the reboot, my phone booted to a white screen with only the status bar at the top being visible. I've tried the triple toggle and the Funtion+Sym+R methods of restarting the phone, but the same thing happens every time the phone reboots. At first the SIM had a PIN set, so the status bar just said SOS only - SIM Lock. I removed the PIN with another phone, then the status bar showed the phone had registered with the AT&T network, but still the rest of the screen was white, so I couldn't do anything with it.
With the white screen, the gesture area would still respond to swipes back and forth across it, and the white screen would show response to wherever I would touch on the screen.
I don't know what I did, but by pressing a bunch of keys as the phone was rebooting, I got the option to reboot or erase entire phone contents. I chose to erase the phone and finally got to set up the phone from scratch. Can anyone explain what just happened?

Hello!
This usually means some software on the phone went catastrophicly wrong thus the need of partial erase.  Could you send me a private message of your palm profile email address?  Have you installed anything to the phone outside our app catalog?  Keep me posted.
