I am using Iphone 4 iOS 4.1 BB 2.10
i want to upgrade my iphone iOS to 4.2.1 but when i try to restore 4.2.1 iOS via itune it gives an unknown error 3194..
i searched in google and many forum it says that try to use new version of itune.
i m already using 10.1 version of itune..
i changed my laptop and tried on other laptop to restore but still getting same error..
i located host file in c:/windows/system32/drivers/etc/ and opened host file in notepad.
but in that host file there is nothing written like gs.apple.com like that... nor ip address is given in host file....
i m using win vista os in my laptop
please can you suggest me any helpful method to get me out with this problem....
Sony Vaio Windows Vista
