I'm just using something like:
"Funds Availability Changes effective 7/21/11: The first $200 of your deposit will be made available on the first business day after the day of your deposit, in accordance with our funds availability policy, in the event that we have to hold any of your deposit for a longer period."
There are a couple of threads with some shorter/sweeter messages as well; it all depends on how many characters folks have to work with on their systems.
