If you’re looking for a good iPhone application to manage your Twitter account, perhaps you should try using Tweetie 2.

Tweetie 2 is an iPhone application that allows you to do things, such as read, post, and manage tweets, view your @replys, Direct Messages, as well as search for users and tweets, view trending topics, and more.

Once you’ve logged into your Twitter account using Tweetie 2, you should see a timeline with the tweets of the people you’re following. When you want to refresh the timeline, all you need to do is scroll up in the timeline and release it and you will be able to view any new tweets.

Tweetie 2 also allows users to upload pictures to websites, such as TwitPic, yFrog, Posterous, and more.

Also, when people post a retweet, you will be able to see that tweet in your timeline, along with the original poster’s avatar and a retweet symbol in the top right hand corner of the tweet.

Tweetie 2 also allows you to view your @replies, as well as your Direct Messages. Also, if you tap a tweet, it will become larger and will tell you the time it was posted, as well as with which application it was posted with.

After you’ve tapped on a tweet, you will also be able to visit any links that the tweet may contain in Tweetie 2’s built in browser.

Tweetie 2 also enables you to manage multiple Twitter accounts, so you don’t have to log out to check another account.

If you would like to try using Tweetie 2, you can download it for $2.99 from the iTunes Store.
