In this new post to his blog Vinu Thomas shows how to install an application onto his S60 phone to access his WordPress blog.
I just came across this S60 freeware today which allows me to manage my wordpress blog on my E71. Wordmobi is a Python app which can be used to perform the following tasks on the blog: create/publish new posts, include images in the posts, view/approve comments and delete posts.
You'll need to install Python on the phone before you can get Wordmobi up and running. He includes screenshots for quick blog setup and the resulting listing of posts it pulls in.
