An invitation to an event held by Nokia and Microsoft has been spread to US medias. It is predicted that Nokia and Microsoft will announce Windows Phone 8 devices. The event will be held on September 5 in New York at 9:30 a.m. local time.
From the invitation, you can see the presence of Nokia Lumia smartphone and Windows Phone. Most likely a Nokia Lumia smartphone with Windows Phone 8 will be announced at that time. However, it’s still unknown how the device will look like. There’s a possibility that the handset is a Nokia Lumia with a 4.3-inch display, which has leaked recently.
Windows Phone 8 is a big improvement over Windows Phone 7.5 which is used on current Lumia handsets. Unfortunately Windows Phone 8 can’t be installed on old Windows Phone devices as it uses new Widows kernel, not Windows CE like before
