It's out! Sorry i'm a bit late because I was on vacation! But here are all the improvements on:
iPad: iOS 4.2 on iPad brings multitasking, folders, AirPlay, AirPrint, and Game Center!
iPod Touch(3rd generation 32GB and 64GB,4th generation): iOS 4.2 on iPod Touch brings AirPrint, and AirPlay!
iPhone(iPhone 3gs, and iPhone 4): Brings AirPlay, and AirPrint!
*Available on every generation(2nd generation or later)iPod Touch, iPhone, and iPad!: New Notes fonts, and new Voice Memos icon!*
I think the biggest improvement is in the iPad because it brings Multitasking, Game Center, and folders to iPad!
