Just installed the newly renamed iOS 4. As my iPhone Developer Center account expired a few weeks ago it wasn’t supposed to work. But it did. The requirement is to have the iTunes 9.2 beta.

First impressions:

  1. It feels a bit slower on my iPhone 3GS than the previous version of iPhone OS.
  2. The Notes application is finally usable – it automatically syncs with GMail or Mobile Me account. Once saved on the iPhone they will show up in GMail instantly.
  3. Love the new unified Inbox. This alone is worth the upgrade
  4. The camera zoom is good enough, adding a bit more functionality to the only camera I cary around all the time.
  5. The new folders feature works like a charm. My 10+ screens are now down to 3 and I have more apps installed. It was becoming completely unmanageable to keep track of my apps.
  6. Multitasking – Done right! Although I don’t think there were more than a couple of occasions when I missed this feature, it’s a welcome addition to iOS.
  7. Places in Photos – I love it!
  8. Homescreen Wallpaper – It sucks! I wish there was a way to avoid it (other than having a black image as my wallpaper)

In short – it’s the upgrade I was waiting for, plus some more. Hoping that Apple will make it a bit faster by the time they release the final version this month.
