** Update **
Guys, following post is no more valid. Even if you get App World on your phone, it will not connect to the server as long as you are in an un-supported country connected through an un-supported career.
BlackBerry App Worldis RIM’s official application store for BlackBerry Apps. Quite interestingly, the app store is not available in all countries. There is a list of countries that are supported and many countries are left out. The store is available in countries like United Sates, Canada, United Kingdom, Australia, Germany France and a few more to buy and download apps. In addition, App World is also available in some countries where people can only download Free apps. They cannot buy these apps. App World with free-apps-only mode is available in countries like China, Brazil, Mexico, Hong Kong, Thailand etc. You can view the whole list of supported countries here.
If you are not in a country where BlackBerry app world is supported, you are out of luck. You can’t download the app world from RIM’s website. Though we have a bit of a workaround for that. You can user your BlackBerry browser to hit this link : http://bit.ly/bbappsworld . Make sure you open it using your BlackBerry phone, not your PC browser to launch the installer that will install BlackBerry app world on your phone. Please note that you will not be able to buy or view any paid app but you will be able to download, use and review the free apps at least.
I have tested this link on BlackBerry Bold 9700 as well as on a Storm 9530. Let me know if it works for your or not.
