Why can't you reset only specific use times on an iphone? I don't want to reset all of them-I want the ability to reset the usage for cellular network data on the date my monthly statement closes. This way I know when I'm close to going over. Is Apple really that lame they don't think we need options? It's not a real big deal on money I just don't understand the logic. I had a Nokia over a decade ago that had it. Is this an app I have to pay for or just jailbreak it.
