These days, you have to keep track of your data and mobile phone utilization. Apparently the iPhone now has one app it can rely on and it is called the Pageonce app.

Pageonce has just made this handy utility for iPhone that keeps tabs on on your minutes and data usage - you can even look over your bill and figure out your current balance. The full feature list includes:

• View current minute balance, rollover minutes, data plan, SMS use, billing cycle, and previous payments on a single page
• Receive alerts when you reach 90% of your limit or when bill is due
• Breakdown information by family member
• View and pay phone bill directly from Cell Minute Tracker

Very cool, but it will be really impressive when we can top-up or change other service details right from the device in an interface like this. Sure, some carriers let you do it by SMS right now, but a dedicated, preloaded app on any handset would be really helpful.

Of course, then carriers would have a harder time pinging you on overage charges… Starting tomorrow you can pick up Cell Phone Minute Tracker in the App Store right over here. Just remember, it’s U.S.-only.
