One thing about Bank of America that I like at the moment is that they are just doing things.  I covered their use of twitter the other day, but its worth placing in perspective.  They are trying many things, including applications specific to the top two business smart phones shown below – iphone and Blackberry.

To me this iterative small, one thing at a time is essential.  The bank gains learning, and importantly gains the following of the early adopters, who will support momentum towards mainstream usage.
