Redsn0w is a development team that was established in Q4 2012. We currently have over 150+ developers working on the project. We have had success with the past few firmwares of releasing them earlier and creating a working ios untethered jailbreak for all of you users out there. With the new iOS 7 we have recently released a working upgrade and a working untethered jailbreak. We hope to hear positive feedback on our project from every one of the members and even suggestions on improving !
Redsn0w supports many iOS devices. It is updated when the Dev Team develops new exploits and features. Depending on the device and the iOS version, redsn0w provides only a untethered jailbreak. "untethered" means that you are able to reboot your device freely without plugging it in. To execute a jailbreak on a device, redsn0w reads a copy of the firmware file and then runs the exploit payload directly on the device.
