Forgive me if this is a dumb question, I've been away from the Kindle hack scene for a few years.
I picked up a Kindle Keyboard 3G when they were first released in Canada. As soon as I got it I jailbroke it and did the linkss screensaver hack. At the time I knew nothing about Linux, now I'm quite a bit more versed and want to start playing around a bit.
My issue is trying to figure out exactly what state my Kindle is in before attempting to apply new hacks like usbnetworking, LaunchPad, or a terminal program etc.
How can I tell what jailbreak I did back in 2010?
Since my Kindle has been updated OTA a few times since then do I need to update the jailbreak?
Right now I'm very interested in getting a terminal emulator going for use with my various raspberry pi projects (

Later I want to find a used non-3G Kindle Keyboard and wire into the serial port and make it a portable terminal I can use with any serial device (ie not just over wifi but direct connection).
Any info would be greatly appreciated, thanks in advance.
