Elcomsoft iOS Forensic Toolkit has been updated to version 1.22. The major improvement is iOS 7 support: passcode recovery, keychain decryption, disk image decryption. As far as there is no jailbreak for iOS 7 (yet), support is limited to iPhone 4 devices only (where the Toolkit works through the DFU mode).
