I am amazed at the applications that have been designed for the iPhone.  I've used a couple for a while.. i.e. Jott, Wordpress and others, but today I went online to see what was new and I was astonished at the number of applications that are available.  I downloaded a couple of free ones and have been playing with them today.  One is for movies.  When I open it, the program figures out where I am, lists the closest movie theaters to my location with previews and  show times.  Brilliant.  There is also a banking software that works with my online banking service.  It gives me up to date balances and will even show my register.  Way cool.
