Personally not gonna do it but here you go.
1: Edit your HOSTS file under “%WinDir%\System32\Drivers\ETC\hosts“
2: Add an entry “updateservices.windowsphone-int.com updateservices.windowsphone.com“
3: Download USAIP and connect to any US-based VPN (ex. USAIP L2TP California)
4: Use username “demo” and password “demo”
5: Connect your Windows Phone 7 to the PC and start Zune
6: Disable WiFi on the phone
7: Open “phone” settings on the phone
8: Manually search for an update within Zune
9: After a few seconds (~15 seconds) disable data connection on the phone
it should then work.
Though looking at the date it probably is an april fools...LOL
