MuscleNerd, a member of the Dev-Team has been involved in the development of tools dedicated to jailbreak the iDevice, has recently announced exciting new details of the upcoming version of redsn0w . With the next release will be introduced to restore the firmware support directly from the tool and without, therefore, to use iTunes.
Even more interesting is also another feature, the Profit tool developed by the Dev-Team, or the ability to downgrade the firmware of the device with the processor and A5 A5X: 4S iPhone, iPad, and iPad 2. Thanks to the use of the new version of redsnow will then be possible to return to a previous version software of the devices mentioned in passing, for example by IOS 5.1.1 to iOS 5.1 or tools are used for the jailbreak able to operate with a software release still previous year. Nevertheless, there are limitations to using redsn0w.
The main, and in some cases insurmountable, limit the use of the tool about the need to have previously saved the SHSH blob of release of IOS you want to restore . The device already used in a native iPhone OS 5.1 because, for example, recently acquired, will not be so “downgradati” to a previous version of IOS.
Users with these devices, when they are forced to wait for new tools to perform the scope of untethered jailbreak iPhone OS 5.1 and 5.1.1. Recall in this regard that the community is continuing to work actively to that effect, as evidenced by the recent advances made both with regard to IOS 5.1 , both in relation to the new iPad . The new release of redsn0w is not yet available, but should not be long to be released too.
