Dumping desc produced almost identical files (the only differences were in
idProduct and iSerialNumber, quite expectedly).

I presume I do not need to re-plug or otherwise re-init the phone after
setting config, correct? (It seems I don't, asking just to make sure.)

I've tried to play with set_config, but without much luck. However, I did
dump_all_config_desc to discover that config index 2 (the one that is "PTP
+ Apple Mobile Device", with bInterfaceClass = 0x0006) is missing from the
output for the "bad" iPhone (diff attached).
Why is it missing? Is there any way to force/inject it into the stack?
