This is a good update, if not breathtaking.
1) I'm not sure if this is something included in the update that no one has mentioned, or just something that's always been there that I didn't notice before, but in Safari, if you've scrolled down the web page, you can tap on the status bar at the top, and it will jump back to the start of the page. This is handy if you want to type in a new URL or do a new search without having to flick up a bunch.
2) I have the Apple Bluetooth headset, and the improvements in the new update are very cool. I love seeing the battery status in the status bar. Before, you could see it while it was charging in the dock with the iPhone (as you still can), but that was essentially useless because the iphone would shut off before the battery status would show, so you had to turn the iphone back on just to see the headset battery status. Seeing the battery all the time in the status bar is a big help.
3) I love the Wifi iTunes store.
4) I also love the new double-Home tap option, but I would like to see one improvement. When the phone is locked (where you need to use the slider), doing the double-tap will bring up the audio controls whether or not music is playing. I have my Home button set to take me to Phone Favorites if music is not playing and music controls if it is playing. So, if the phone is locked, I would like to have a double-tap also take me to Phone Favorites - this would be very convenient, especially when driving.
5) The Blackberry-esque double-space=period option is cool, but I'll need to keep reminding myself to do it.
