Microsoft opened its Windows Marketplace for Mobile application store to software developers on Monday. This step has been taken as a result of Apple’s iPhone App Store success.

MS has approved 29 countries that can submit applications to Windows Marketplace and wait for approval.

This will provide Microsoft with an opportunity to get on the global market of cellphone applications, a spot that Apple has been dominant after the iPhone Application Store.

Software developers are able to include their own marketing materials and will gain revenue based on sales.

The neat future is that there is a money back guarantee offered to the estimated 30 million customers of the Windows App Store.
