Some little known improvements added in iPhone OS 3.0… Some stuff here is listed at Apple’s site but only for some context. Thanks to James O. for confirming pre-3.0 behaviors.
YouTube – You can login to your YouTube account to access your own favorites, but also:
- Bookmarks in the YouTube iPhone app are merged with your YouTube favorites.
- Your YouTube playlists and subscriptions are fully available and editable on the iPhone.
iPod
- Podcasts no longer have shuffle as an option (which makes sense for most podcasts), therefore they will play in order without having to turn off shuffle mode.
- Scrubbing speed is adjustable by sliding your finger up and down the screen (for instance, “grab” the slider, move your finger down, then slide left and right to scrub slowly, or slide back up to scrub more rapidly).
- Podcasts have a 30-second instant replay button.
- Podcasts can be played at 2x or .5x speed (I believe only Audiobooks allowed this previously).
- Search is now available (just like Remote, and several other apps in 3.0).
General
- Search is a double-press-home option.
- Search targets are customizable (you can omit Audiobooks, for instance).
- Camera app’s “roll” button shows your last pic.
- Rotate Stock app to get bigger chart. You can tap a point to see the price at that time.
- Notes (and possibly other places) will parse addresses for linking to Google Maps.
- Screenshots view is integrated into the description page. Scroll down and immediately scroll left/right.
Phone app (and/or Contacts)
- Outgoing calls have an special icon in the list view.
- The line items with multiple calls (”Josh Forman (3)”) will list duration and time of each call in a nice table format.
- Share Contact option emails a VCF.
