I discovered too late that I had already updated to the latest firmware which hasn't been cracked yet, but it turns out I didn't have to jailbreak it at all. I just deleted my Amazon account completely, factory reset the Kindle device, never logged in with an account, and now I just keep it in airplane mode and sideload EPUB files from Calibre onto it. Works great.

I wasn't trying to troll you; I'm sorry it came across that way. I understood why it was disrespectful to use that word for people, but I didn't realize there was a problem with using it in general. Clearly I have more to learn here.

I'd be interested to understand more about why you find this usage of the word "retarded" offensive. I sometimes use the word as a synonym for "stupid" or "idiotic", but would never use the term to refer to a person with a developmental disability. I'm curious if your experience is different. Do you feel the word should be eliminated from usage entirely?
