What is a good iPhone App for managing my bills & expenses?

I am considering getting an iPhone. I currently have a BlackBerry and one of the things I like about it is I have an app that lets me easily track the expenses I occur while I am out. Can anyone recommend any similar apps, or perhaps even better apps, for the iPhone that will help me manage my finances?

Hi, if you need an app to track your expenses I'd recommend BudgetCare: www.budgetcare.com

It is not a "finance manager" but a simple app with onlymost important features to record expenses and view the stats. It shows nice diagrams and pie charts and I found them rather useful. Look at screeshots and you'll see it yourself. Hope it helps!
