Textpattern mobile theme
I wrote this post a while back. The content can still be relevant but the information I've linked to may not be available.
If you're a fan of Textpattern, you might be interested in Mobile Textpattern, which is a Textpattern theme that has been developed for mobile by Oliver Ker. The theme allows you to administer Textpattern sites via your smartphone with an easy to use single screen interface. You can edit and publish articles and comments and it works well with the image selector plugin upm_img_popper. The theme is simply installed by uploading the theme folder and choosing the theme in the Textpattern admin.
I've used Mobile Textpattern with my HTC Sense Android phone and it works great!
