Identify port on old Nokia flip phone

Question

It's an old 2007 Nokia 2760 flip phone.

What port is this? I have searched everywhere but can't find any info. If this is a USB port, what USB plug it receives, or if something else…?

The official manual simply ignores that port

Answer 1

It's a port for the Nokia CA-50 USB data connectivity cable. Used by phone models 1200, 2600, 2650, 2680, 2760, 1650.
