SwitcherPlus Gives Multitasking To iPhone Lock Screen

SwitchrPlus is a free Cydia tweak that allows you to use all the multitasking goodness of your iPhone even in the lock screen mode. The tweak lets you activate or deactivate the camera LED (iPhone 4 only) directly from the multitasking tray. Note that this tweak is for iOS 4 only.
You can select your favorite apps for both the Lock Screen and the Unlock Screen mode. These apps will always be displayed at the front of the switcher list. Other settings include Triple Home Press Action (you can set this for No Action, Torch Light or Wiggle Icons), Open to iPod Controls (Always or When iPod playing), smooth scroll, Kill Prior Exclusions, and so on.
SwitcherPlus is available free of cost in the BigBoss repository.
