Finance, Mobile Media, commonly used Mobile apps?

Given all the buzz about the new iPhone 3G and the new applications rolled out for it via 3rd party suppliers. Does anyone have applications that they use more often than not? I'm surprised that I have yet to see any major online brokers (Scottrade, Ameritrade, etc) create mobile applications with the exception of E*Trade's app. for Blackberry devices.



It makes immense sense for E*Trade to roll out their Mobile Pro app for Blackberries since most high finance folks that I know use Blackberries religiously but I suspect more people will begin use the iPhone for more finance with its new functionality...alot of these online brokers need to get the ball rolling, and quickly, with respect to creating mobile applications for more phones outside of Blackberry. We have a new post on our blog discussing this in greater detail.
