I have multiple iOS devices... (two iPhone 4's, one GS, two G and two iPads). All of the devices sync to different machines and under different user profiles. I realize that each device has it's own update so what I would want to do is download one version of each OS put it on a centralized HD and point the update process to that file instead of having to download a copy for each device. Can anyone tell me how to do this. Having to download multiple copies of of a 600MB file is really a pain.
Thanks
