reSpring iOS5 is a new tweak released in Cydia, very simple and can be useful for some users because it allows a respring to your device by pressing an icon which will be added to the Springboard.
Although there are many ways we can do a respring to our device, for example using SBSettings or other tweaks available in Cydia, reSpring iOS5 is intended for those who use these tweaks and is limited to making a respring by adding an icon on Home Screen.
reSpring iOS5 is available for free in Cydia, repo ZodTTD.
