jailbreak Kindle PW 3

I really don't want to go through the Jailbreak process, mainly because I am not a developer, and don't quite understand some of the instructions.

But i really want my Collections to be synced between my device, my Amazon kindle ebook list (which may not be possible if I have non-Amazon books?), and Calibre.

My Paperwhite serial number if G090 G105 7232 ONO7
Firmware version is Kindle 5.9.4 (3278740046).

My computer is a Mac.

Can this device actually be jailbreaked (jailbroken)? Will I be able to sync Collections? Are there directions that a nondeveloper might understand?

Thanks very much for any help.
