    Verizon Iphone 4..4.2.10 installed
    I redownloaded the IOS5 GM CDMA. I was able to extract it to my desktop. I know it's a good file since when I put the IPSW extension on the file it comes up as an Apple File (the Cube with the note on it) I go to do an upgrade via Itunes and it says Firmware Not Compatible..I am using Windows 7. Anything else I can try? If this doesn't work, I will just wait until it legitimately comes out:)

    You need iTunes Beta 7.

    And, DFU Restore Install.

    I thought you could use Windows to install it? Mac Only?
