Auxo, the jailbreak tweak that will be available in the coming days on iOS 6 (iOS 5 to follow), makes great use of the iPhone 5's extra space by showing preview cards of each app. rather than a simple icon. Unfortunately, since there is no jailbreak for the iPhone 5, we will have to wait to fully experience Auxo, however it runs smoothly on the iPhone 4.
The app switcher now displays elongated card-like icons that serve as a visual representation of their respective app.
The playback controls page, accessible by swiping to the right, now shows more information about the media playing than before, while also sporting improved playback buttons (inspired by the new music app's player design).
The settings page (two swipes right), previously known as 'the useless volume slider' page, now features a useful brightness slider as well as settings toggles which, like the brightness slider, can be used as shortcuts to enable and disable system functions, previously only accessible through the settings app.
The tweak should be available in Cydia in the coming days. No word on pricing yet.
