As I posted before, I have been looking for an app to replace Tweetie/Twitter for iPhone 3.x for a while now and I think I’ve finally stumbled upon it. While it might not satisfy every need I have, it does everything that I need and then some.
With version 2 for iPhone and the new iPad version, Tweetbot really has taken the lead in the Twitter client arena. While I have not tried out Twittelator Neue (what a strange name), I have settled on Tweetbot both because it fits my needs on the iPhone and has an iPad app that is beautiful and functional.
I recommend that you give it a try for yourself.
