Icons are the way that you interact with your phone to open a app. An icon pack is an app that will replace your icons with styleized versions. The purpose of this is to make your phone look better and to give you some options if you're tired of looking at the same thing every day.
Many people don't realize that icons are even changeable, and so they spend their time looking just at the default ones that come with their phone. Well, there's a whole exciting world out there waiting to be discovered. Take a look around our site here at BestIconPack.com and see if you like one of our designs -- and then give it a try! 9Careful, it can become addicting to get your phone customized the way YOU want it instead of just taking it how it comes out of the box!
