Hello everyone

I hope add the function to monitor iphone used 3g/wifi band switch.

I know I can do these in my app, but I wonder if there is way to monitor all band switch usage of iPhone?

I noticed that there is an app http://itunes.apple.com/ca/app/download-meter-for-wi-fi-gprs/id327227530?mt=8

It claims:

Works with any carrier (iPods are supported too!). Requires no login/password to your carrier's site. Does not require Internet connection to get traffic usage statistics (works even in Airplane mode) because it gets information on traffic from the device, not a carrier; this means it won't cost you anything to view current traffic consumed, even while roaming in a location where traffic is very expensive.

Allows the user to adjust consumed traffic for today or the current month to match traffic amounts reported by your carrier. Stats on the screen are updated every second. Measures traffic in real time with up to byte precision. Separates traffic into incoming and outgoing, Wi-Fi traffic and mobile Internet traffic.

It looks like it gets the band switch info from carrier site, but they also said it gets info from device. I am really confused.

Welcome any comment.

Thanks
