Microsoft just announced today that an update to their Windows Phone 7 OS called Mango is going to be released this Fall. Mango will provide about 500 new features and enhancements such as Internet Explorer 9, visual voicemail, even more social media integration etc. They also announced 3 new hardware partners: Acer, ZTE and Fujitsu and we might see the first Nokia Windows Phone 7 device in time for the holiday season!
Microsoft seems to have listened to their customer’s feedback and Mango will contain many new features aimed at making Windows Phone 7 more competitive against Android and iOS. You can see some of the videos of the Windows Phone 7 Mango OS Update below [from Microsoft and Engadget]:
