DirectionBar is a neat little tweak that makes the iOS status bar more informative. If you ever wanted to know which direction you were headed without having to open the Compass app, then this tweak is for you. Once installed, a live compass appears on the status bar right next to the Wi-Fi or cellular data icon. Moving your iPhone will result in the compass arrow moving accordingly, always pointing north.
Under the settings for DirectionBar, there's a selection of different compass arrows to choose from. Nine different icons will point you in the right direction, but if this isn't enough you can download additional icons from Cydia. A custom icon can even be created in .png format and installed into the directory /Library/Application/Support/StatusCompass/ if you're feeling creative.
Changing the status bar compass icon requires a respring to take effect. The tweak includes a Respring Now button under settings. One thing missing from this initial release is the ability to enable or disable the status bar compass from Settings. For now, if you decide to switch off the compass icon you'll have to uninstall the DirectionBar tweak.
DirectionBar is available on Cydia from the ModMyi repo free of charge. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
