Used to happen all the time when I had my HTC mogul now happens with my touch pro. A bunch og googling and searching these forums and Howardforums tells me that it is due to the phone going in and out of roaming or switching towers.

One intersting thing is that whenever I drive up to my house, my phone turns on at exactly the same place in my driveway every time. Found out that it happens when my phone picks up the signal from my airave. I verified it by unplugging the airave and trying again several times and it did not turn back on. Plugged the airave back in and it started again. So, it is most likely that capturing or switching a signal location is what causes your phone to turn itself on.

One other theory that was given to me is that it also happens when your phone either picks up or loses a data connection.

Hope that sheds some light.
