The iPhone Dev-Team has released the latest version 0.9.15b1 of its famous jailbreak utility redsn0w for Windows and Mac. Redsn0w 0.9.15b1 adds some new features like re-restoration of A5 devices, which allows hassle-free restore to the iOS versions which are no longer being signed by Apple. For example, if you are on iOS 5.0 currently and wanted to restore your device to 5.0.1, you will not be able to do so as Apple will allow restore to only the newest iOS version (6.0). So once Apple stops signing an older firmware after a newer firmware is released, you will not be able to restore to that older firmware in iTunes.
With redsn0w 0.9.15b1, you can restore to a firmware version even if it is not being signed by Apple. The only thing you will need is the correct shsh blobs for the same. A tutorial will be posted soon on this topic. Stay tuned to Blog O'Nerd.

The other features added in redsn0w 0.9.15b1 are as follows:
- Cydia now included in the tethered 6.0 jailbreak on A4 devices.
- automatically “Just Boot” tethered when qualifying A4 device connects in DFU mode.
- untethered 6.0 jailbreak on old-bootrom 3GS.
- untethered 6.0 hactivation on any 3GS or iPhone 4.
- directly restore pre-A5 devices to earlier firmware — no more complicated 15-step how-to’s with stitching, iTunes errors, and “hosts file” concerns.
- fetch new signed blobs for any IPSW (present or future — no redsn0w update required) using Extras->SHSH Blobs->New.
- block the BB update for any 3GS or iPhone4 restore (past, present, or future — no redsn0w update required) using Extras->Even More->Restore.
- deactivate any iPhone, useful for testing your official unlock status through iTunes.
- activation status shown on “Even more” page.
- significantly more info returned by “Identify” button when device is in Normal mode.
- tethered jailbreak of ATV2 supported (but the only thing available for it is the SSH2 custom bundle available here — no Cydia yet. Must use “Select IPSW” for tethered boot of ATV2 for now).
- auto-exit WTF mode for older devices with broken buttons.
- any time a set of blobs is fetched remotely (from Apple or Cydia), redsn0w also saves them locally (and will check there first if you click “Local”)
