I get the same error when trying to register for Ping, or downloading iPhone3G app updates. I am now using iTunes 10.0.1, which I just installed.
I have never previously received this error, however, I just fixed error 9808 yesterday, which required a change to 'Settings|Control Panel|Internet Options|Advanced' to uncheck 'Check for publisher's certificate revocation' thanks to advice I read elsewhere. I don't know if they were related, but fixing the 9808 error simply exposed the 1202 error.
I am surprised Apple haven't acknowledged this problem or posted a solution - this error has been recently reported in many places, including multiple times on these support discussions!
I just got this error when I tried to redeem my itunes gift card. I read on another discussion that you should try to right click on the "redeem" link, copy, and then paste into a new browser window, accept the security prompt. It worked like a charm! I got right in, no error, redeemed my card and happily went shopping. I don't pretend to know what causes this error, but this simple work around did the trick. I would be interested to know if it works for others too. Good Luck!
This problem is related to having your computer, Apple device, etc
(from your current physical location) being unable to resolve/connect to
the following site/domain names and their related IP address(s).
The following table is presented to help explain/clarify this issue:
Site/Domain name | IP Address
phobos.apple.com | 188.8.131.52
deimos3.apple.com | 184.108.40.206
albert.apple.com | 220.127.116.11
gs.apple.com | 18.104.22.168
itunes.apple.com | 22.214.171.124
ax.itunes.apple.com | 126.96.36.199
If ANY of these sites/IP address are unresolvable (via PING for example)
then the ability/usability of Apple's iTunes (and the Store) will suffer.
To have yourself verify that (if) you can connect to these sites, you'll
need to open up a MSDOS/Command prompt window
and then type "ping" (without the quotes) and one of the (above) listed sites.
For example you would type the following at your command prompt:
ping phobos.apple.com (then press the return/enter key)
which (should) give you results like this:
pinging phobos.apple.com.akadns.net http://188.8.131.52 with 32 bytes of data:
Note: Anyt response other than "reply" (like Request timed out)
indicates a problem resolving the site's name to an IP address
and (generally) has NOTHING to do with your (normally functioning) computer
as this is dependent on the ISP (Internet Service Provider) that you are
using to connect to the Internet (like Sprint, Insightbb, etc) with.
The 'key' here is that it's the ISP's responsibility to (properly) resolve
the site's name to (one or more of) Apple's sites.
If (however) Apple (itself) is (currently) experiencing a DDOS attack
(Distributed Denial Of Service) upon one (or more) of it's sites, then THAT
would explain a possible cause of the problem.
However I stress THAT is NOT the problem since I can connect from my Insightbb
(ISP provider) at home but (currently) can not connect at work via their ISP.
This is (also) WHY the "tag" of the FQDNSN (Fully-Qualified DNS Name)
is listed as http://akadns.net since that is the ISP/Router resolving the DNS name!
I hope that this has helped shed some light as to WHo's problem this REALLY is,
and will help to stop the Apple-User 'finger-pointing' game in it's tracks!
