What’s new in official iOS4 and iTunes 9.2?

I just upgraded to iOS4 this morning, have a quick review on the iOS4, it is pretty much better than beta version (of course). Beside the nice multi-tasking  and folders features, the are lots of new features and improvement in iOS4:

iOS4 new home screen

i just notice now if you setup your gmail/Google App mail in email setting, you can now sync your Notes to your Gmail/Google App account.

And when you check your notes, you can choose different account to retrieve the note. That is awesome!

And from iTunes, you can organize your apps easily and support folders as well. Also, if you installed some File Management App like FileApp, you can easily add files to your iPhone without any 3rd party software needed.

Which is nice add-on features!

Great work, Apple.
