windows phone 7 mango update voice recognition and controlAccording to the next major update to Windows Phone – the ‘Mango‘ update, will be arriving on September 1st.

Multiple trusted sources have confirmed to us that the start of next month will see the new OS, available to developers over the summer, launching on new handsets, as well as becoming available to current WP7 customers.

The launch date, we now understand, has been chosen due to its importance in tieing in with IFA, Europe’s largest consumer electronics show in Berlin, and means that companies like Samsung, Acer, ZTE and LG will be able to show off new devices with Mango installed.

Its not clear what this date (if accurate) will mean – new devices on September 1st, Mango update available to existing devices, both? Still it’s only a couple of weeks to wait to see if this particular tip turns out to be true or not.
