Good to hear. Does this also mean that pages load
faster?

FYI after much experimentation, research and
testing the mobile site has
been lazy loading images [1] since Thursday 18th August. This means if you
do not see an image you will not download it. We have taken care to ensure
users without JavaScript can still view images and that most users will
barely notice the difference.
We are currently crunching the data this change has made and we plan to
write a blog post to reporting the results.
In our experiments on Japanese Wikipedia we saw a drop in image bytes
per page view by 54% On the Japanese Japan article bytes shipped to users
dropped from 1.443 MB to 142 kB.
This is pretty huge since bytes equate to money [3] and we expect this
to be significant on wikis where mobile data is more expensive. In a
nutshell Wikipedia mobile is cheaper.
As I said blog post to follow once we have more information, but please
report any bugs you are seeing with the implementation (we have already
found a few thanks to our community of editors).
