If you are looking for a Twitter client you may want to check out TwitBird Premium (iTunes link) which just came out with a new version and is free for Christmas before they raise the price, to what I don’t know.  I downloaded TwitBird and giving it a try next to my Tweetie 2 which costs $2.99. I like Tweetie 2 but if you want something that is free TwitBird Premium is worth a look.

Some of the features are:

• Supports 2 accounts
• Landscape mode
• Search for nearby tweets
• In-app badge shows number of unread tweets
• Tweet music, your voice and video
• Push notifications – free from TwitBird user to TwitBird user, in-app purchase for global notifications ($2.99)
