## Features
- Legacy iOS Kit supports all 32-bit iOS devices, and some 64-bit devices (A7-A13)
    - Newer devices only have partial support with limited functionality (e.g. sideloading and other utilities only)
- Restore to signed OTA versions (iOS 8.4.1 and/or 6.1.3) on A5/A6 devices
- Restore to iOS 10.3.3 (signed OTA version) on supported A7 devices
- Restore supported devices to unsigned versions with SHSH blobs
- Restore to unsigned iOS versions with iOS 7 blobs (powdersn0w)
- Restore supported 32-bit devices to unsigned iOS versions "without" blobs
    - Includes downgrading iPhone 2G, 3G, 3GS, iPhone 4 GSM and CDMA, iPod touch 1, 2, 3, iPad 1
    - "without" is in quotes because powdersn0w uses iOS 5/7 blobs for touch 3 and A4 devices, but it is signed for everyone to use
    - Other devices however are true blobless
- Tethered downgrades/restores to supported iOS versions for some 32-bit and A12/A13 devices
