Can you drop the battery? (no)
It looks like you can't drop the battery. Honestly I'd say that's the ONLY security feature that matters now days. I had a "friend" who was getting located by the cops in a city and dropping her battery was the ONLY way she could see the cops chasing her quit moving her direction and start scratching their heads. (other than ditching the phone entirely of course).
These things do not turn off. Sure, I'd trust that MAYBE Blackberry can make a phone that reliably turns off. MAYBE. But without the backup of killing the power entirely just forget it. Also, how can you have a hacker friendly phone that DOESN'T allow you to drop the battery.
