I have my iPhone on FW 4.3.2 & I am using Mac to unlock. In step 2, after I browse the \"iPhone2,1_4.3.2_8H7_Restore.ipsw\" file, it prompts me \"iTunes will erase and restore your iPhone to iOS 4.3.2 and will verify the restore with Apple.\" If I click restore, it says \"The iPhone could not be restored. This device isn\'t eligible for the requested build.\" Any idea how I can get away with this error ?

Same thing happened to me, it's because an Apple server was blocked in my Hosts file. Go to this folder: /private/etc/ Locate the "hosts" file and open it up. See if there is a line that looks like this... #74.208.10.249 gs.apple.com If so, remove the "#" at the beginning and save the file. You may need to adjust permissions before you can save. After I did this, iTunes allowed the custom firmware to load. Good luck!
