Google Translate, the amazing app that takes speech or text and outputs into any of over 50 languages (including Icelandic, Haitian Creole, and Maltese), is finally available on the iPhone. You can type or speak in any of 15 languages, and hear your translations spoken out loud in any of 23, which is really impressive.
Learning a new language is hard. All those new grammatical rules, the new spellings, new tenses, irregular verbs--it's a serious pain.
