Rumours of two updates to WP7 emerge - first to be announced this week

We’re expecting in the next few months to see the first Windows Phone 7 ‘service pack’, which has been called ‘massive’ by some developers, but we’re still in the dark about Microsoft’s plans for the platform.

Writer of the upcoming Windows Phone Secrets book Paul Thurrot has apparently managed to get a sneak peek into what Microsoft’s plans are for the near future, and he's revealed that the Big M is actually already planning two major updates to the fledging mobile OS in the coming year.

The first is the one we’ve been hearing about even before the system launched back in October. Other than the internal name - ‘No Doughnuts’ - there’s little new information on this update that’s relevant to consumers (unless you have a perversion for CDMA location stacks), so we’re expecting the previously rumoured Copy and Paste, third-party multitasking, and voice-navigation on Bing maps to be the poster-features for the update.

The previously unheard-of second update, tentatively called ‘Mango’ for some reason, also sounds like another major overhaul of the system. According to Paul, Mango will include Internet Explorer 9 with Silverlight and HTML 5 support, as well as gesture controls.

This latter update is also reportedly labelled as an ‘Entertainment’ update internally at Microsoft, so there may also be much-needed improvements to the Zune Player software on their way as well.

We shouldn’t have to wait long to find out exactly what Microsoft has in store, as it’s rumoured the company will be unveiling full details on NoDo later this week at CES 2011.
