I have the profile question as well. I can't work out how to put the phone to silent.
This is a great phone over all but since it is missing the ability to quickly change between silent and not silent it is fatally flawed. Currently I am turning it off when I am somewhere it cannot ring. I have used these type of phones since 2003, I've never seen one that lacked a silent mode. That is not really acceptable. What a disappointment.
For now, I'll be switching back to my U2800A. Maybe this phone will get better software in the future.
