I had a samsung galaxy s duos back in the days. Then bought a i phone 4s so i linked my s duos to my iphone 4s(had reseted my s duos after the link). Now i got a new Device(Sony xperia z2). When i try to link my iphone 4s with my z2 its says on my i phone that i can only link once. How i can the save from my 4s to my z2?
