Hi, at the last phpMyAdmin team meeting, we started a discussion about an eventual mobile-ready version.
Some developers mentionned the possibility of using Twitter Bootstrap for this, while other developers were not sure about the feasibility of this, due to the amount of data to show when browsing a table, for example.
We would like to take the pulse of the community about such a development; it might become part of our list of ideas for Google Summer of Code 2014.
