Personal organizer PageOnce has a great iPhone application that I think many will find to be incredibly useful. Like its desktop sibling, PageOnce for iPhone is a feed aggregator the likes of Netvibes or MyYahoo. The only difference is that you're feeding it account information for utilities and services to get a quick overall view of your various balances and spending activity.
I've been using the application for the past few days, and have come to rely on it almost exclusively to keep track of bank accounts, mobile phone usage, and my Netflix queue. In fact, it's currently the only way to track your Netflix account short of visiting Netflix.com or another Web-based queue manager in Safari (although this is coming soon), but will do far more if you're willing to spend the time plugging in all your accounts.
PageOnce for the iPhone keeps each feed in its own container and opens it up like a nice large pop-up that can be scrolled through and dismissed with a quick touch on the screen. You can see all types of accounts that have been up through PageOnce on the Web. Missing, however, is a way to add new accounts from your phone. This will hopefully make it in later editions.
Privacy nuts should be a little wary of putting this much of their personal login information in the cloud, but the good news is the application can be set to forget your password every time you exit, keeping it safe if your phone is lost or stolen. Also, as mentioned in previous coverage, PageOnce uses bank-level security to keep accounts from being hacked.
Below is a demo of PageOnce for the iPhone and iPod Touch in action.
