I was recently jolted into learning more about mobile web design when called upon to perform a usability evaluation of a mobile web site and create some wireframes. Mobile web design is a new frontier for many UX types — although surprisingly some folks have been working in this area for several years. As a consequence, there’s some good info available to us newbies. Here’s what I’ve come across so far. Additional recommendations welcome!
