iPhone OS 4.0 Update

So yesterday's presentation has finished and some rumors have been confirmed while others have been put to rest. Apple announced that there will be 100 new features coming with OS 4.0 this summer, but they chose to only focus on 7 'tentpole' upgrades, as they put it. Here they are:
1) Multitasking!!! they are doing it in their own way...which looks to save more battery power than most multitasking phones.
2) Folders: people like me have 11 pages of apps and it's annoying to flip through them all to get to new ones...folders will allow you to group apps into....you guessed it! folders.
3) Email update: OS 4.0 will allow for a unified email box and the ability to open up attachments in seperate applications...for example...open a word doc in a word processing app. This can become very useful.
4) iBooks: the iBook store/reader from the iPad will be added the the iPhone...whooopy....
5) Enterpise Update: if you use your phone for business, look for better protection, Mobile device management, wireless app distribution, ssl vpn support....
6) Game Center: this is kinda big for the gaming industry...apple finally realized how they can really profit in the gaming world. 3rd party companies like OpenFeint offered acheivements & leader boards for a wide variety of games...now apple will do that for all games and allow you to have a friends list who you can invite to play games, gift apps too, and compare accomplishments.
7) iAds: tired of seeing those ads in your free apps? well apple will be allowing companies to put interactive and more entertaining ads that won't take you to safari in their apps. I'm just hoping this doesn't get overboard.

Some other new things worth mentioning...ability to change home screen wallpaper, ability to change passcode to use letters, faster app switching, face detection in photo app, spell check, and possible video conferencing????

Expect an announcement about the next iPhone to come out in mid-June. The worst thing I heard at the presentation was...OS 4.0 will not work on the first gen iPhone, and multitasking will not work on the iPhone 3G....BOOOOOO.
