Random Reboots

I'm not sure why but in the last 2 hours my Versa has rebooted about 4 times.  I have it on VIBE at work and hear it vibe like I have a message.  When I look at it I see the Verizon logo which it only does at startup.  To my knowledge it has not done this before.

Anyone else experiencing this?  Just curious...

I have not upgraded to 3 yet, will likely do that this weekend.  Almost impossible for me to get to the Verizon store before tech closes at 6:00pm.   I'm 30 minutes away and get off work around 5:00.

No its not in my pocket.  Its setting in front of me on my monitor stand at work when this occured.  It did it several times yesterday morning and I have not noticed it since, nor did I notice it at all in the 3 weeks prior.   Its in the same spot today so I'll keep an eye on it.

Just strange.  I'm not 100% sure it shut off and back on or rebooted but are there any other instances where the Verizon Logo would appear on the small keyboard screen without the phone having been touched in one case for at least an hour?

I did not notice the shut off or anything.  Just noticed the vibration like I got a text message, looked a the outside screen on the keyboard and saw the verizon logo.   Opened the phone, normal screen inside, no new messages, no missed calls, no new voice mails or anything.   

I'm not worried about it right now unless it continues.
