Apple customer care is saying if i used headphones other than apple in iphone? - 1

It will damage headphone jack, please tell is this true?

LOL not at all headphones are headphones. Thats like them saying if you break your screen its cheaper to buy a new phone/ipod. No it costs like 50$ to replace the screen. They say that because tey get paid to say that its in their contract they just want to make more money off you which is extremely unfair. If your headphone jack is broken it probably just needs to be replaced find a computer store to do it.

No. All plugs are the same size.
