Download the new iOS 4 GM version now and install it even when you are NOT a developer.
YES! GM version doesn’t need UDID registeration, however it does need iTunes 9.2 Beta (Mac only).
SO, If you are a Windows User, you CANNOT get the iOS 4 before 21st June.
If you are a Mac User, get it FREE today!

iTunes 9.2 is now available for Windows.
I have tried restoring my iPod touch 2G to iOS 4 GM and it’s working awesome.
Redsn0w 0.9.5 for Windows is also out to enable Multitasking and Background Wallpapers on iPod touch 2G and iPhone 3G.
