I've read the jailbreaking instructions and I obviously don't quality for it based on my firmware version.
Questions:
1) Is it worth hoping a future jailbreak will be announced for my firmware version?
2) Are the following instructions accurate in stopping OTA updates so I can 'freeze' my current firmware version for a potential future jailbreak?
You should block any OTA updates before allowing the device to connect to the Internet.
To prevent OTA updates, add the OTA blocker directory (folder) name to the top level of visible USB storage.
The blocker directory is named: update.bin.tmp.partial
Use that exact name, no additional extension, no contents.
3) What do you find the *most useful* things you can do once you have jailbroken/rooted your Kindle? So far I've noticed that putting a better PDF reader would the most beneficial to me.
Thanks in advance!
