Tinyumbrella probably modified the hosts file on your computer, try putting the file back to how it was before you installed Tinyumbrella.
See this Apple doc for more info -> iOS: Resolving update and restore alert messages
If you have installed software to perform unauthorized modifications to your iOS device, that software may have redirected connections to the update server (gs.apple.com) within the Hosts file. You may receive an error 1004, 1013, 3194, or "This device is not eligible for the requested build" in this circumstance. First, uninstall the unauthorized modification software. Then follow the steps to edit the Hosts file and allow iTunes to communicate with the update server in the Blocked by configuration (Mac OS X / Windows) > Rebuild network information > The hosts file may also be blocking the iTunes Store section of iTunes: Advanced iTunes Store troubleshooting.

I didn't install tinyumbrella on this macbook, I said I knew how to use it, but I installed it on my other macbook, and used it with my other iPhone (4s) as well. This iPhone now belongs to my daughter and thats why i want to take out the sim-lock. The provider that the iphone is locked for is way to expensive for her, so i need to remove it. And as I bought the iPhone 4 more then 24 months ago, i can remove it legally. So on this computer that I tried it on, theres is not anything installed that may have modified the host file
Thanks for your attempt to help and thanks for the link(s), but I already tried those steps more than a hundred times. If you know anything else, please let me know.
ps: if I sound rude, please don't take it personally, its just that english is not my mother language, I'm German.
