Twitter app free for iPhone

UberSocial

UberSocial for Twitter has been called the Swiss Army Knife of Twitter apps. This nifty little software from Ubermedia, Inc allows you to create a "favorite users" list. You will never miss a tweet from your friends again. For those who get a lot of tweets, this feature will save time scrolling through hundreds of messages. But the app has many other features. You can mute users or hashtags for a specific period (or permanently). Menus can be customized so only the most used items appear. Facebook users will be glad to know that they can post Tweets there.
