Loren Brichter is releasing Tweetie 2 for iPhone.

It’s a big update — more worthy of a “2.0″ label than most applications. I’m most excited for full persistence (the application remembers precisely where you were when you return to it), and threaded conversations.

Interestingly, this will not be a free update for users. It will be a new application in the App Store, and will cost $2.99.
