Ramdisk on 3.x firmware (currently beta release) is a simple img3 file, that you can decrypt using vfdecrypt keys. But vfdecryp can't decrypt img3 files, so you must download command line utility called img3decrypt. For easier access, put them in /usr/local/bin

In Terminal.app enter: img3decrypt e rrestore_ramdisk.dmg restore_ramdisk_decrypted.dmg Ramdisk_IV Ramdisk_Key

Where restore_ramdisk.dmg is image of restore ramdisk (for example 3.0 beta 1 iPhone GSM firmware restore ramdisk is 018-4793-1.dmg), and restore_ramdisk_decrypted.dmg is decrypted image, that you can mount and explore from Finder. Ramdisk_IV and Ramdisk_Key is a decrypted keys that you can find in vfdecrypt page or in Info.plist from PwnageTool FirmwareBundles folder (when Dev Team include support for this firmware).
