iPhone’s usage statistic is not so useful. It displays the total call time only. Since most of the mobile phone plan have limited call time, it is vital to check the usage for specific period. A recent new program iCall would be very useful. iCall can check the total incoming and outcoming call limit within the specific time range you choose. There is no need to worry there will be expensive bill. It works pretty well. There are more incoming and outcoming call details can be found in the program. Also, You can also choose to delete some log.
To install, you need to have a jailbroken iPhone. And add “myapps.110mb.com/iphone.xml” as the Install source. “iCall” will be available under “MyApps” category. After installation, make sure you restart the iPhone (switch on and then turn off the iPhone).
