I would hope they have some feature for automatic backup to your phone over bluetooth or such today.
Bluetooth is slow. The transport is 3Mbps at max, if you subtract all the headers from different layers, you may have like 1.5-2Mbps practical transfer speed.
They do transfer, but it's not automatic.
WiFi is a little faster I guess? In the primitive days people used the EyeFi.
