I don't have anything from Cisco, but I went to their site and tried to download the 12.4 IOS. Naturally it said that I couldn't because I wasn't registered. :roll:

If you are registered and still can't download, then I guess you should email them or something and ask about it. If you are the owner of one of their products, and you are registered on their site, you are more than entitled to be able to download the update to it.
