I can safely say that my daughter's iPhone has ruined our lives. We've had it for five days. Yes, there are some built-in parental controls, but Apple has blocked anybody from offering a software program that will turn the dang thing off (I'm talking about texting and calling) at a certain time every night. I have a daughter who is addicted to her phone and the battles are humongous to get her to do anything but text.
There are plenty of good programs with good parental controls for the Android and Blackberry, but thanks Apple for not allowing us as parents to turn the phone off at night. I know about Mobicip, which is a great company, but they can only turn the internet off, not texting or calling. When you have a kid who can and will text 5,000 texts a month, we need something that eliminates the battles at home and can automatically turn the thing off when it's bedtime. We're all losing sleep. Most parents, when they get an iPhone for their kid, don't realize that Apple, unlike Android, has chosen to place more importance on children's privacy than parent's ability to place restrictions on their kids' phones. I plan to take the iPhone back and get her an Android.
