ESL apps for Android handsets

Anyone who has an Android phone (such as the G1, Nexus One, Motorola Droid/Milestone) might be interested in this list of English related apps available for their phones. I've taken a quick look through and a lot of them are dictionaries/thesauruses related to a particular language, but there are some general ESL apps as well. I don't have an Android phone, so I can't really test any of these out so would be interested in hearing from those who do and who have tried some of these out.
