Today, Twitter was updated to the 4.0 update, giving it a new look and some of the features the full site received. You now have 4 tabs at the bottom; Home, Connect, Discover, and Me. Home is basically your timeline, Connect shows your mentions and interactions, Discover will show your trends, while Me shows you your Twitter stats and let's you check your DMs. The new Twitter update is pretty cool, it looks nice, seems a bit speedier, and works almost as well as the desktop version. Being able to see who is retweeting your tweets and following you is a great addition. You can download Twitter for the iPhone, iPod Touch, & iPad for FREE from the App Store.
