The iPhone Dev Team has released a new version of RedSn0w that is 0.9.10b8b. As mentioned on the official blog “The 0.9.10b8b update to redsn0w makes the zip files more compatible with the native Windows explorer (which doesn’t like leading slashes in the filenames).” You can read more by visiting the official website and looking for Update#3b.
If you are looking for jailbreak 5.1 on iPhone 4S or any other device you need to know that this RedSn0w 5.1 jailbreak is tethered and as mentioned in one of my previous post we are very much sure that the untethered 5.1 jailbreak will be very soon available for public. So keep in touch and join my blog from below box so that you can be informed immediately once the 5.1 untethered ipad3 jailbreak is released which hopefully will be compatible for all idevices i.e. iPhone 4S, 3GS, iPad 2, iPod Touch etc.
