On my latest fiddling of my Nokia N8 trial that I got from WOMWorld, I found some interesting new features on it. Most likely on its new OS that now supports integration of Social accounts to your contacts where you can copy directly your contact’s social media profile images and use it on your contacts. You could either use their Twitter or Facebook profile images.
One caveat of the method is that is uses low resolution photos which are blurry when navigated to contacts profile. Nonetheless, it’s still useful and will minimize your time in doing some manual shots and replacement.
