A long complaint of iOS users is that Apple has yet to provide a solution to quickly change certain settings without entering the dedicated Settings.app. Many believed that, once Notification Center came, Apple would provide an optional widget for the feature that would allow things like Wi-Fi and Cellular Data to be turned on and off without entering Settings. This did not come, however. 

SBSettings is a well-known jailbreak tweak that allows users to swipe across the top of any screen on an iOS device and see a series of toggle switches that allow you to perform certain tasks, such as the aforementioned ones. However, many iOS users do not like the idea of jailbreaking, whether it be for one reason or another. 

Luckily, a tool was recently released that allows users to place icons on their homescreen that, when tapped, will bring them directly to that specific preference section in Settings. The setup is simple:

Step 1: Go to the following webpage on your iOS device: http://iphoneza.co.za/IconSettings/ and scroll down until you see the header "Single Icons (new .mobileconfig method. Use if you only want to install a few icons):" 

Step 2: Find the specific preference pane that you would like to open from the homescreen. A good example would be Brightness, since users tend to change that a lot. 

Step 3: Click on the Brightness link. The Settings app will launch and you should see a screen similar to below:

Step 4: Click the "Install" button, type in your passcode if you have one, and allow the tool to install. 

Step 5: Once the install is complete, click the home button to exit Settings and there should now be an icon on your homescreen that says "Brightness."

Step 6: Simply click the "Brightness" icon on the homescreen and you will be brought to the Brightness preferences in Settings. 

Repeat these steps for any other Settings panes that you would like to use.
