My question is on iPhone 3G and iMessages.
My iPhone 3G does not have and never had iMessages. The iPhone 3GS of a friend has.
Day 1: I got my friend's iPhone, put my sim card into my friend's iPhone, connected it to my Macbook only to charge it. Later, I removed my sim card again from his iPhone, put his back in and gave it back to him. I did not do ANYTHING on his iPhone, nor change or delete any setting.
Day 4: We both meet again at the same place. He later tells me that he received my SMS of that Day 4 (true). We did not exchange anything that day. He did/does not receive them immediately "live", but only on that day when we met.
- How did my SMS get on his iPhone? Bluetooth, Internet, Provider?
- How does iMessages connect and authenticate to get the SMS of the corresponding sim card?
- What does iMessages store on the iPhone itself to still be able to connect?
