What does this Korean word mean?

I was talking to my friend on message and he said '옛날꺼? ' What does it mean? I broke my phone and he asked what phone and I told him iPhone, then he asked this. Please help, I'm still texting him and I don't want to leave him waiting, thanks^^

It means 'old off' apparently but it could be wrong

'the old one?'
옛날 means old times
꺼 means thing.

It means "… An old one?" the implication of old is "ancient" or "antique"

There's a typo, he should have written 까 not 꺼

It means old off i guess
