You can expect the first Nokia WP7 handset, sometime during the end of this year. If new reports are to be believed, Nokia could unveil the device even a lot earlier than that. The company is holding a Nokia World event in London on October 26 and 27. This is the time when Windows Phone's Mango update, which is said to change the way WP7 performs, is scheduled to come out. Naturally, this is a good occasion to launch the new device. With the arrival of this update, all media attention will be focussed towards the platform.
Having said that, Nokia could alternatively launch the device during the end of the year (in December perhaps) as earlier reports had suggested. We think that the company would make the announcement during October about a launch date of December. As of now, the Nokia World seems like the best bet to show off the device. However, it was expected that Nokia could announce the device during the already concluded Nokia Connection event, which was held in conjunction with the Nokia CommunicAsia 2011. Everyone will be eagerly awaiting the announcement of the "market disrupting device" or the Nokia N9, so we think that it was wise of Nokia to keep the suspense alive.Source : Nokia WP7 Phone In October?
