When the iOS 5.0.1 upgrade and restore is applied to the iPad 2, does it also update the firmware? The firmware level associated with 5.0.1 is 9A405. The firmware download from appldnld.apple.com is named iPad2.2_5.0.1_9A405_Restore.ipsw. The file size is 732MB, so it looks like a firmware + iOS combo. Is this the same file that would be downloaded when the update/restore is done via iTunes?
