Add Brightness Control to Now Playing Bar in Multitasking Tray on iOS 4.x [Jailbreak Tweak]
Thanks to a new tweak available in Cydia, iPhone brightness can now be adjusted from the multitasking tray, found just under the music controls with App Switcher Brightness.
This is a nice alternative to the brightness control in settings, or ever the one in SBSettings, and as of version 1.0.1, it fixes the well know bug where the brightness adjustment wasn’t permanent after locking the device.
A point to note is that this WILL conflict with another tweak from Cydia called App Switcher Volume. Therefore you must use any one of these tweaks, not both.
