I mentioned this in another thread but thought it might garner more attention here. I keep seeing people indicate that this or that problem is fixed by a "battery pull." While I understand that a frozen/unresponsive phone must have its battery pulled in order to get it to reboot, I am failing to see what this accomplishes when your phone is functional. Is there something that a battery pull does that shutting down your phone does not do? I was trying to work it out in my head and couldn't come up with anything. Memory is cleared when you power it down. Cache is stored on the flash card, so that doesn't go away. Nothing stays powered up during the shutdown... So, help me out here. What does it do, that holding down the power button and selecting "Power Off" does not do?
