PW2 Questions about adding "Jim's Board" to my PW2

My Kindle PW2 is running firmware 5.8.9.2. I would like to jailbreak it. Apparently the only way I can do that at this time is to crack the PW2 open and tickle it via its internal serial port.

Thanks to dhdurgee pointing me in the direction of Serial Jailbreaking your fw >= 5.6.x Kindle for Dummies I am in the process of doing this.

I have already obtained Jim's board. I have already cracked the case open w/o damaging anything that I am aware of. Out of its case entirely, the Kindle still works. I am as amazed as you are! ;)

While reading the Serial Jailbreaking thread I saw a post from kaz572 about mounting the serial board permanently into the PW2 case. That seems like a reasonable thing to do. I have been ESD trained. I can solder, have tools, patience, and time. Oh, and a Dremel. Don't leave home without it! Before proceeding I have a couple of questions.

Q:1 Does leaving the serial board attached, obviously continuously powered, cause any significant change in the Kindle's battery life?

Q:2 Has anyone other than kaz572 done this? Care to share your experience and any tips you might have? For example, what's the best place to mount the board?

Thanks :thanks: in advance.
