The developers have released a way to semi-tether your pre-tethered iOS 5.0.1 Device.
**Once you've Jailbroke your iDevice on iOS 5.0.1, you'll need to install the Semi-Tether in order to turn your device on if it dies or has to reboot.**
ZoomIsBack! is an incredible app in my opinion. When updating to iOS 5, you were unable to manually slide to zoom in or out. This tweak is pretty much self explainitory, it brings the ability to manually slide to zoom in or out. Now in iOS 5, you did have the ability to zoom in or out just by pinching.
