I am from India. Today I was surprised to see data sense app in one of my friends new lumia 820 purchased only yesterday. I heard that this app will be coming with GDR 2 update but it is already there with new L820 having firmware version 1308.0001. My L820 ( purchased 2 months back ) is also having firmware version 1308 but with no Data Sense and I could not find it in apps store also. Can any one shed any information regarding this ?
