    The iPhone SDK will only run on a MAC

    Because the iPhone SDK will only run on a (intel) MAC and you need this to load the Beta OS.

    iPhone OS 4.0 is only available for iPhone developers who are intended to use it to develop and test iPhone applications.

    To develop iPhone applications you need to have a Mac running XCode. There is no Windows version of XCode and there never will be.

    This is why Apple are ignoring Windows users at this time. All of the devs are Mac users.

    It will be available to the general public in the summer. The last major release (iPhone OS 3.0) was released to the public on 17 Jun 2009 - it's possible that it will be a similar time of year this time round, but no real guarantees.

    do you know how the beta expiration dates work ? does it expire before the next beta or do you have time in between betas ? Or does the whole beta program just expire once it goes GM ?

    Actually, I think you could install iPhone OS 4.0 using a Windows laptop. But you'd still have to be a registered iPhone developer to install it.

    Installing the OS doesn't require XCode. The OS is a separate download from XCode. It's supplied as a .dmg (Disk Image) file, which is a proprietary OSX archive format. (Under OSX, you can "mount" a .dmg file to your file system, and once it is opened it appears as a directory in your file system.)

    There's a third-party command-line utility available for Windows called dmg2iso that will convert a .dmg file into a .iso file. You can then use a third-party .iso mounter, or simply burn the .iso to a CDRom.

    Inside the archive is a single .ipsw file. This can be installed (after first registering your phone's ID as a developer phone using the developer website) using either iTunes or the iPhone Configuration Utility, both of which are available for Windows.

    So, technically, this IS possible.
