It's similar to MarketEnabler which let you access paid apps in Android Market, but add funny functions as
1. Support Android Market 3.4
2. Support download & buy paid app in Amazon Appstore outside USA.
As you might have known, android market and amazone appstore will stop you from downloading and tell you that it's not supported in your region. Why? Because the server's checking your ip address countries as well as your provider. For amazon users registered with us credit card and billing address, it's frustrated when you're not in usa.
Market Unlocker will force visiting Market and Appstore via a proxy, that makes traffic looks like from USA. Unlimited access any more.
Find out more details in Android Market by search "Market Unlocker". I also attached an apk, but check out from android market is still recommended.
Believe it will help you.
