Microsoft's own photo stitching application, 'Photosynth', is now available to download from the Windows Phone Marketplace. Photosynth allows you to take spherical 3D panoramas with your Windows Phone and upload them to Microsoft's own online service at Photosynth.net. From there you can then share, via a link, to your own blog, Facebook or Twitter.
To be able to install Photosynth, you will need to be running Windows Phone 7.5 (Mango) or higher. We've personally tested it on a Nokia Lumia 710 so far and everything seems to be running fine.
If you install Photosynth, let us know how you get on (and share your masterpieces!) in the comments.
