iPhone OS 3.1 – Steve Jobs announced the debut of iPhone OS 3.1 and it’s available today. But base on my test, it’s still not available on iTunes. Hopefully, it can be downloaded later today. But for those using ultrasn0w to unlock iPhone, please be reminded not to update to this version until iPhone Dev team gives you the green light.

iTunes 9 – As expected, Apple releases a new version of iTunes – iTunes v9. The new version looks pretty great. Now, you can use iTunes to manage the iPhone home screen and move the icons around right from iTunes. The other feature you’ll love is Home Sharing. Finally, iTunes can support multiple computers and you are allowed to copy songs, TV shows, etc. with up to 5 computers. As Steve mentioned, “You’re going to see all the computers you can share with, and you’ll see the contents — you’ll be able to drag that and copy it to your library.” That’s cool and it’s a long-awaited feature. The other features come with iTunes 9 are improved syncing, genius mixes and iTunes LP.
