how to fix error 1635?

Same problem with Ipad 2!!

I suspect the problem is related to non-US stores. I also have this problem, from South Africa

btw, I get this error on my macbook Pro running 10.6.8 while my ipad2 was updated to IOS5 when this error started.

Same error on my iPad 2 to, running on South African store. Because of this I am also unable to use my Vodacom 3G, only wireless works and iPad wont even connect through iPhone. I have friends who are using Cell C with the iOS 5 update with no problem. Apple please help!!!

PARTIAL SOLUTION: This actually worked, didnt help the update to work but got my 3G working, sweet!

The EASY FIX:

On the iPad go to your Setting, click on Cellular Data and then click on APN.

No matter what they told you in the past, the setting must be: iPhone.Vodacom.za(not internet)

If you now go back to your web browser, it SHOULD simply work (you might need to give it a second or two and might need to switch off your iPad and boot again).

If this DOES NOT work then:

Call 082 155 (if you are on Vodacom) and wait till you hear the iPhone options. Press that and then when the operator comes on, tell him/her that you would like to register your SIM card for the iPhone APN. He will ask you for your number, and some security questions and then you will be done. You will hear the usual “Wait between 1 and 6 hours and then try again”

Once you have done that, simply go to the EASY FIX step above and enter your APN settings.

This will sort you out and you can once again surf away on the iPad
