LockSpring allows you to respring with the help of a button available in LockScreen

  Today we add a new one called LockSpring to the long list of tweaks available in Cydia. The functionality of this tweak is limited and it boils down to adding a button to the LockScreen of our iDevices. This button gives us the option to quickly respring our iDevices. Normally this is impossible to do without the existence of a dedicated button, but the tweak eliminates the need to install more complex ones that also contain this function. LockSpring is available for free in Cydia and should theoretically work on any iDevices.
