Can my iPhone 6s Plus iMessages sync with my iPhone 3GS?
Is it possible to sync my iPhone 6s Plus messages with my iPhone 3GS? I if I send an iMessage from the 3GS, it appears on my iPhone 6s Plus. But if I send an iMessage on the 6s plus, it doesn’t appear on the 3GS. Is this an issue with one of the phones, or does the 3GS run on a too low software?
iPhone 3GS, iOS 6
