Microsoft Corporation has signed up multiple software partners for its upcoming cell phone software marketplace, including Web music service Pandora, game publisher Electronic Arts Inc and social site Facebook.


On Tuesday Microsoft Corporation has plans to discuss those partnerships and conduct demonstrations of the software store  set to launch later this year.


In February, Microsoft revealed plans to open Windows Marketplace for Mobile in the second half of this year, but had not announced software partners. Along with a list of initial partners, the company said it expects many of its existing 20,000 mobile phone software partners to offer software.
