Not sure why they changed this... I like to leave my ringer and SMS alerts on at night, but do not want an email notification sound. I used to go into settings/sounds and just slide the new mail sound off at night and turn it back on in the morning. Now the slider switch is gone. I have to go into the available sounds and actually select none. Not impossible but definitely an extra step. Am I missing something? I still miss my blackberry sound profiles - not sure why they don't build this in it seems like it would not be that complicated. As far as I know they only way to use sound profiles is to jailbreak.
