Re: [iPAQ] ipkg FUBARed my iPAQ :-(

Just a note on doing backups. If you want to do a complete
backup to CF, you can simply do this:

dd if=/dev/mtdblock/1 of=/path/to/cf/card/someimage.jffs2

Then (using a recent bootldr), you can actually write the image
back to flash, and have your system back up and running in
literally a couple of minutes!

I wrote up the process on the wiki if that wasn't sufficient.
