Version 1.2.1 is out. There have been no functional changes, except for removing two obsolete lines in the orientation extension, and for supporting installation on a larger variety of KT models. In other words: there is no urgent need to upgrade.
UPDATE / Documentation:
I just realized that the included documentation isn't really useful for newcomers who never installed a hack on their Kindles. No worries, it's really simple:
- Plug the Kindle to your computer.
- Copy the file named "update_launcher_1.2.1_install.bin" to your Kindle. Make sure to place it directly in the top-level directory, not in the "documents" subdirectory or in any other subdirectory.
- Safely eject the Kindle from the computer.
- On the Kindle, choose Menu -> Settings, then Menu -> Update Your Kindle.
