Twitbit is a Twitter client for iPhone and iPod Touch but preferably for those with 3G connection as this application will function just like an SMS would by pushing the notification to the front regardless what you are doing.

Features

• Browse and send direct messages
• View your and other people’s profile
• Browse users’ followers and following list
• Start or stop following people
• Follow conversations as far as they go
• Mark tweets as favorites

• Upload pictures to Twitpic
• View current, daily, and weekly trends
• Never miss any Michael Jackson news ever again
• Search Twitter to find out what everyone’s saying about that great new Twitter iPhone app
• Receive alerts for new mentions and direct messages
• Keep tabs on all of your accounts, without the hassle of constantly switching between them
• Add as many Twitter accounts as you’d like
• Quickly switch between accounts
• Securely authenticate with OAuth
• Communication with the outside world is always secure
• Browse previously viewed tweets without a network connection
• Catch up on old tweets while you wait for a new set to be downloaded

Features that I wish the developer adds in the future versions

• A “Retweet” button with RT or Via prefix
• Ability to view full resolution of profile photographs similar to “Tweetie” in iPhone
• Ability to choose other twitter photo upload sites like yfrog and etc.
• Ability to add links into bookmarking sites such as instapaper and etc.
• Color shades for Replies, own tweets and Direct Messages
• Ability to change themes

Obviously this twitter client have lot’s to improve on but I’m quite sure the developer will do a revamp on the current version soon to make it on par with other clients or even better with PUSH notification feature ^_^

This is a race to make the best twitter client ever! For those who needs a push notification for twitter, this is the client for you! However at at steep price at $4.99 it can boost it’s popularity by having some discount promotion in the future!
