If I am constantly switching between two SIM cards on one unlocked iphone (3GS), what happens to my message history? Is there a separate message history for the first SIM card, and then when I change to the second SIM card I only see the message history for that card?
Is it the same with Whatsapp?
I assume the contacts are centrally stored on the iphone and they are the same regardless of what sim card.
If you sync to iTunes, then does it sync message and call history for both SIM cards?
Thanks!!
