Looks like Amazon is finally going to fix the ;installHtml issue. Over the last few days, one of my articles has been getting a lot of hits from lab126. (hi SBR-6729!) (Note to Amazon, might want to hide your referrers from your lab126 domain.)
Guessing they'll fix both vectors soon, finally wiping these in the factory as well as updating busybox etc.
Sort of weird it lasted this long. I assumed they were tacitly supporting the community by leaving that in, but I'm now thinking it was just lack of time.
At least the Kobos are finally on par.
All right, good luck everyone! Grab a jail-breakable Kindle before yet another hole closes.
