Almost all I've heard and read about since the launch of a certain new, improved iPhone last week is applications - the popularity of the new apps store, the best free apps... it's been, quite frankly, apps up to my ass. But I'm not easily impressed. There's only so long I can be enthralled by Tetris or Scrabble on my phone (and that's quite a long time, but we all get bored eventually).

What I'm really interested in knowing about are honest-to-goodness useful applications that could actually make my life easier (my imaginary life, where I own an iPhone 3G, that is).

And Jott is one of the few apps to actually get me interested.
