Microsoft has officially opened the doors of its Windows Marketplace for Mobile to developers. Windows Mobile code monkeys with a Windows Live ID, valid taxpayer ID, bank account and $99 to spare can sign their life away up for a vendor account with Microsoft. Once approved, developers may begin submitting their Windows Mobile 6.5 applications for inclusion within the Marketplace. Similar to Apple’s App Store, each application will be reviewed and approved according to Microsoft’s application submission guidelines. With new Windows Mobile 6.5 handsets on the horizon and the Marketplace now open for applications, things in the world of Windows Mobile are starting to get interesting. Umm, right?
