it will be much less power-efficient, when jailbreak you could schedule the kindle to wake up once per 15/30/60 minutes to fetch the new data, set it as screensaver and then go back to sleep.
replyIt's easier to load up a page in the Kindle browser, but more fun to jailbreak :D
replyI also didn't want the browser bar at the top.
Fair enough. I did consider jailbreaking my Kindle but I am afraid of bricking it.
replyBricked it few times in the process of figuring out more stuff about it, but luckily mine has a UART pads and I was able to restore it every time. A bit more involved as it's 1.8V if I remember right, but if you're careful it should be easy, provided you have the time.
replyAlso fair - bricking it was definitely one of my main concerns.
replyAfter going through this process though, I'd say as long as somebody has basic linux knowledge, chances of bricking are pretty low.
