jTwitter - a Twitter client for the mobile phone

I've been looking for a decent Twitter client that will work on my Motorola RAZR, and just now I found jTwitter. I'm on pay as you talk as I don't use my mobile that much and I tweet as much as I can and also follow a respectable number of people so using SMS would be too expensive, and using Opera Mini or the default Vodafone browser to navigate to the Twitter mobile page is a pain, not to mention expensive as you have to pay to download all those images and things - using a dedicated client is the way to go. I already use the Google Mail client, so with this as well I should be able to keep in touch more easily.
