I don't know how much help I can be with the jar tool. I can tell you what I did though.
I used adb to get the /system/app/Launcher.apk file. The I extracted the file. So now I have the .apk file and a folder with all of the files in it. I then copied the .apk file to make a backup of it, just in case I needed to push it to the device.
Ok now I am set to do the editing of the files. I use Linux so I started gimp up editing an image. Then saved the image, keeping it the same size (56x295 - something like that) as the previous file. The files size (k/mb) will change. You need to keep this as small as you can.
I then started up Archive Manager, I think that you said that you use winrar or something. You might want to try 7zip, not sure though. Onward. I opened the .apk with the archive manager. The allowed me not to have repack the archive. I then dragged and dropped the edited .png file into the same folder I edited it from, into the same folder browsing though the archive manager. This did nothing more than update the .apk archive with the edited file.
then I pushed the file back to the droid. I hit the end button to turn the screen off and then menu x2 to get into the interface again. This refreshed the interface. and my edits were there.
That is about it. I'm going to copy and paste this reply in the forum so others will benefit from your question.
