All this while, I thought Cellspin was my solo Symbian plug-in for E71 to blog.
But I was wrong.
Here comes a freeware called WordMobi that allows you to blog on WordPress, including self-hosted sites like mine, using the WordPress platform.
Not only is the upload quick, you can also add tags, photos, videos and personalise. You can make certain words in bold and italics for instance.
Just Google it and you shall get the download link. If you find a better app for Symbian, feel free to share.
