Among a host of other excuses, I've witnessed that going in and out of EVDO will turn the phone on. OTH, I've had quite a few WM/PocketPC/PPC/WinCE devices through the years, PDA's, phones and PNA's. Virtually all have turned on for no apparent reason from time to time. Every forum I've been on going back to the Casio E105 days has had posts about it. No one has ever given a iron clad reason why that I'm aware of (signal, software, alarms, maitenance, etc.). I think MS considers it a feature. Like having the device turn on repeatedly to tell you it's battery is running low, killing said battery significantly faster. If I leave my phone in my basement office where signal is low, the phone will turn on repeatedly and it's not unheard of for it to stay on for prolonged periods too. My wifes Palm 755p will never do this.
