I am downloading the iOS7 update image for my iPhone over a high-speed connection. I want to update my wife's phone too, which is synched to her computer at home (where we have sloooow internet).
Is there a relatively painless way to transfer the installer to her computer at home on a usb drive, so we can update her phone as well?
Edit: mac on both ends and same model of iPhone.
I found the ipsw
on my computer here:
~/Library/iTunes/iPhone\ Software\ Updates/iPhone5\,1_7.0_11A465_Restore.ipsw
I will try placing this in the same location on her computer and see if iTunes will recognize it.
