Twitterrific 2 arrives, and it's NICE!
I first used Twitterrific 1.0 on the iPhone and really liked it, but found some limitations. It was one of the first apps on the iPhone and it has been a staple of my iPhone non-stop for the last year+.
Now with the release of Twitterrific 2.0 (via TUAW) I have been playing with it for the last 24 hours and it is well designed (there is a learning curve to “understand” how to find settings or adjust accounts), but to review, search or post, it is wonderful, simple and beautiful.
If you are looking for a twitter client for the iPhone (free/ad-supported or paid) Twitterrific is worth a good long look.
