I'm hooked on my iPad, I admit it. And like most, I'm constantly adding new apps. Now, they don't always stay. Many are on for only the length of time it takes to play with them once. I tend to look for apps that have free-try-me versions before forking out any cash. Not all apps work as promised.
What a lot of people don't realize is that a lot of these apps have additional settings that must be accessed through the Settings panel.
So, if you have an iPad, iPhone or iPod touch, and you haven't looked at those settings in a while, take a look. You might be surprised at the information there. Some, like Pages and Numbers, only give you the software version number. Others can give you more control over how the app syncs or looks on screen. Check it out, and be prepared for some interesting info.
