If you are on a jailbroken device, than SBSettings is a must have app. SBSettings will let you control vital settings of your iPhone as easy as swiping your finger on the screen.
Some of you might know ( and still use ) BossPrefs, so you will have an idea what SBSettings is all about. SBSettings can be found in Cydia, in the BigBoss repo , which is a default repo in Cydia, so you should have no problem finding it.
Once installed , you access it by swiping your finger from the top of the screen down. When yo do that a new screen will slide down where you have basically 3 action areas: Toggles, Actions and Info.
