There are many VPN services that do that for you. Here's how it works:
Your connection is identified by an IP address, which is where web pages or streming videos are sent after you request them with your browser. Likewise, any service on the internet has an IP address, which is where your browser requests pages.
The IP is typically, but not necessarily, assigned to you temporarilry by your internet provider. Large ISPs and servers usually have pre-bought IPs which never change.
There are companies, most notably MaxMind, who keep track of where each IP is geographically located. This is known as geolocation.
A service may use geolocation to determine whether to serve you or block you or send you to a localized version of its pages.
Now, here's the trick:
A VPN service (a virtual private network) is a service where you can channel all your communications to the outside world through a remote server. For example, if the company you work for offers you VPN, all your computer's activity could be channeled through a server inside the company network and thus your computer would appear as to be part of the company's intranet.
There are other commercial VPN services that offer no-question-asked, full broadband IPs to appear as if you were browsing from the location identified by their server's IP address. They usually have a list of servers and locations to choose from.
Commercial VPNs have generally a latency cost. Since all your communication go through a foreign server, data has to travel a lot more to get to your computer. This is usually perceived as slower bandwidth. For this reasons, some VPN companies now offer "virtual country" IP addresses, where the server is located near you, but the geolocated country corresponding to its IP is one of your choice.
I tend to travel a lot and use one of these services to access Netflix, BBC etc when I'm abroad. It works perfectly, with the added advantages of giving me an encrypted connection to the internet (typically one's connection is exposed in open WiFIs like hotels and airports) and of being virtually anonymous, because my real IP is hidden.
That said, though, Unblockus seems to be different from a VPN. I was misled by their page title when I answered above ("Unblock-Us - smarter faster VPN").
The way their system works is that they take over your DNS configuration. What are DNS? They are services that translate a site name, like "netflix.com" into an IP, as explained above, like "69.53.236.17". By taking over this service, when you type "netflix.com" in your browers, the IP address returned will not be Netflix's but their own. They can then proceed to "proxy" your connection just like a VPN provider would do. In other words they will ask for the page or video on your behalf, and then send it, or stream it, back to you.
The concept is very similar to a VPN with simpler configuration, but it will have some (many) caveats.
- it won't work with services specified by IP
- it will throw stern warnings if the site is encrypted. or make the connection less secure (I hope not!)
- it generally will lower your security because all the data will transit through their servers unencrypted (not so with a real VPN provider), although the communication to their servers might be encrypted.
- their service might be selective: they might not proxy some servers like Google.
