Blackberry
Currently I am working on a project which needs to fit on a iPhone Blackberry, because the technican engineers do not need a laptop to complete the task, but is absolutely required to track their work.
That RIM baby is actually a powerful device, but it disappoints me in not even understanding simple JavaScript commands and CSS properties like the meanwhile everywhere used display:none.
At the beginning of that project, I initially intended to create a rich and and easy to use Ajax interface, but now I have to do it with step by step forms.
Currently, I have reached now page number 13 (today is Friday, the 13th) with each of a maximum containing five fields fitting the display size and content.
I found a nice Blackberry HTML reference which helped me out a lot with the development. Maybe it will help out you, too.
By the way, the iPhone is the best mobile device to display internet content. Everything I tried until now was working so well. Good work, Apple!
The new Blackberry series hopefully becomes more CSS/JavaScript power.
