Downloaded iTunes 10.5 and iOS 5 beta 3. I extracted my iOS5 file, and have s+clicked restore trying to put the firmware in but it wont let me put any of the files in, nor am I seeing a file with .ipsw. Anyone have any wisdom I want to play!! lol
Were you able to extract the .ipsw file from the .dmg to a temporary folder, or to your desktop successfully? To open it, you need to:
In iTunes on Windows, shift-click and press on Restore, then browse to find the file.
In iTunes on Mac OS, option-click and press on Restore, then browse to find the file.
Remember - we are currently on Beta 3. I'm guessing Beta 4 will be available within 2 weeks so you might want to wait for that as it will have stability improvements, etc.
