Big day for Microsoft today. It is set to unveil new Windows phones at 11am today at London’s Centre Point. Last week we reported on its supposed iPhone killer, the ‘pink phone‘. Today it announces its first smart phones with Windows Mobile 6.5.

Although precise handset details are still a closely guarded secret we have found a little bit about new integration services for the Windows phones which will be announced. These include My Phone and Marketplace. My Phone lets users back up and manage their photos and apps for free as well as other content from their phone including contacts, appointments and text messages directly onto their PC.

People can also publish their photos from the My Phone website or the phone directly to Windows Live, Facebook, My Space and Flickr as part of the free service. It’s also possible to go online to map the last known location of the phone from when it was last synchronised. There will also be a premium My Phone package which will immediately locate a phone’s current location on a map, will remotely lock a phone and will post an ‘if found’ message to its screen. Initially this will be available only in the US but it will come to Europe in the ‘near future’.
