Wavelog is an amazing application that allows you to blog from your mobile device. All the major providers such as Blogger, WordPress, Facebook, Picasa, Joomla and many more are supported.
It isn’t a free application. You have to pay a few dollars for this application. There is a free trail though. It has limited features. It allows you to have only one account for the first 30 days unless you’ve already bought the application. As a matter of fact, I’m using the app right now to post this article. Hope it helps you people
