I am using Iphone 4.Before I was using Samsung Galaxy Duos. I have set up gmail in my iphone and is synced with my ipad. It is also synced with my Samsung mobile. ( Messages get deleted from all these 3 at the same time.) When Iam not at home if anybody opens my samsung mobile how can I get a notification on my iphone? Is it possible to deactivate sync in my samsung mobile from my iphone?
