iPhone OS 4.0

I'm back on the grid! Some new iPhone 4.0 highlights I think are interesting...

Finally some multitasking on the iPhone. With a real status bar showing the items that are running. Cool.

I love the ability to host push notifications on my own servers instead of Apple's. I hate depending on a 3rd party for this kinda stuff.

Also the ability to create a folder by dragging one app on top of another will greatly enhance my organizational skills (I'm O.C.D. in this area - deal with it!)

Also, unified Inbox (now I don't have to check 10 email accounts) and iBooks (looking forward to this).

GameKit - The additions to gaming are pretty cool. Just like XBox Live - neat and unexpected from Apple, but makes sense since gaming on the iPhone/iPad is huge!

iAd - not excited about this as an end-user (I'm already bombarded by too much Marketing - my eyeballs hurt), but a potential revenue stream with a 60/40 split between developer and Apple.
