Good news for the Un-lockers and the Jail breakers!!
The news may be stale for some, bur for those who haven't heard of it, here its: The iPhone Dev Team has released yet another RedSnow version which adds the support for backing up the precious activation tickets resulting from the SAM unlock. That makes things a lot easier as users won’t have to backup tickets manually anymore.
Users can now backup arbitrary directories, and RedSn0w will by default backup the /var/root/Library/Lockdown which is needed to preserve your activation ticket. The pace at which these progress are being made, more support for this SAM Unlock feature are to be expected in future.
Following are the direct download links from where you can grab the copy of the latest RedSnow version.
