Thanks for developing this. I just downloaded it today and after working with it here are my comments:

Agree that the avatars and number of posts bubble could be deleted. They just take up room and don't add value to a "mobile" app version.

Also there should be a way to navigate directly to the newest posts in your subscribed threads

I think one ad is acceptable but two is unusual for an iPhone app. In the FT app, having the same ad on the top and the bottom of the page seems really OTT.

Appears you have fixed the crash problem iOS 4.2.1.
