Here are some details for you to think about:
So you’re a tweaker, and you’d like to do more with the Kindle Touch than Amazon allows, but the previous methods of jailbreaking Amazon’s e-readers don’t work anymore. Fortunately, a new exploit allows you to hack the first-generation Kindle Touch in three easy steps.
Here are the instructions, via The Digital Reader:
Download the Kindle Touch jailbreak from Yifan Lu. It’s actually a special MP3 file designed to work some magic.
Connect your Kindle Touch to a PC and drop the MP3 file into the e-reader’s music folder.
Play the MP3 from the Kindle Touch’s “experimental” menu. The device will install an update and restart.
What can you do with a jailbroken Kindle Touch? Not much, at the moment, although you can already download a custom screensaver mod from Lu’s website. In the future, Lu expects developers to write apps for the device, tweak the interface and add support for additional file formats, such as ePUB. “This first jailbreak is really for these developers,” Lu writes. For everyone else, it’s just a preemptive move before the real modifications roll in.
If you’ve got a Kindle With Special Offers and are hoping to remove the ads, this hack may be the beginnings of a solution–as long as you can sleep with a guilty conscience–seeing how users previously figured out how to strip ads from earlier jailbroken Kindles. For that reason, if you have any interest in modifying the Kindle Touch, you might want to install this exploit before Amazon covers it up.

Kindle Touch Jailbreak
What does the jailbreak do? All it does is open the door to unsigned modifications by installing a developer key into the device. It does not modify any existing files and it only writes one new file.
It does NOT do anything useful or noticeable other than this. You must find and install modifications that extend the device (the jailbreak only allows that to be possible.)
After installing the jailbreak, there is NO side effects at all (battery life, stability, etc). However, because you are no longer limited to Amazon's sandbox, you could potently damage your device by installing modifications that are improperly coded or by incorrectly using the modifications. Just a warning.
based on this i think your problem is NOT jailbreaking the kindle but something more fundamental in the way you are trying to make modifications.
this might be a case in point:
