I'm very interested in this but am a noob. what is back swiping on virtual keyboard?

Please share the old files, or if it is possible can you tell us where to find them. Is it imperattive that we reflash?

@art:
I hope I can remember what I did... It's basically all in fanoush's post above, though (his script):

First I unpack the fiasco image:
One of the files I get is rootfs.jffs2. I used this one and deleted everything else that was in the image.
Then I find a free loop device (usually /dev/loop0) with "losetup -f" and attach the rootfs-file to it:
Next I set up the block2mtd-module to work with the loop device. Honestly, I have no idea what all these things are... I just do as I'm told:
I didnt do the "modprobe jffs2", "modprobe mtdblock" because those are not modules in my kernel; normally you will have them as modules and use modprobe as described by fanoush.
(I learned that you have to compile block2mtd as a module, though, otherwise you can't cleanly undo all of this.)

Next you mount the device:
...

daperl, the N900 doesn't use JFFS2.
