Well, take this news with a pinch of salt. First of all, Nokia has not yet officially launch Nokia Lumia 910. We do not know if it even exist and Nokia Lumia 900 has not been officially announced in many other countries. So, is this product page of Lumia 910 by Typhone by the Dutch phone retailer real? I guess you will have to decide.
In the product specs, it states a 16GB internal storage and a 1,830 mAh battery. Lets wait and see if Nokia Lumia 910 is real.
