The iPhone Dev Team released redsn0w 0.9.15b3 a couple days ago (when iOS 6.0.1 was released) with improved bug fixes and also includes the ability for new iPad mini and iPad 4 users to save their iOS 6.0 blobs to Cydia. Muscle Nerd recommends users to stay at 6.0, but of course this is nothing new if you’re an experienced jailbreak user:
Save your 6.0 blobs with redsn0w's SHSH->New button (connect device 1st). Also
I recommend staying at 6.0 *if* that's where you are now

Directions are listed below:
Update #2 (Nov 1): Version 0.9.15b3 fixes the redsn0w “error 2601” that Windows users were seeing using the Restore button. It also fixes a related Windows iTunes error 14 for stitched files. Note that if you have a baseband, you should probably avoid stitching and simply use redsn0w’s native Restore (not iTunes).
Those lucky recipients of new iPad minis and iPad4s on Friday can use this redsn0w to save your 6.0 blobs off to Cydia. First connect your new device and turn it on, then use redsn0w’s Extras->SHSH Blobs->New and point it at the 6.0 IPSW.
