Selling my current iphone question.

[powersrus]

I was just wondering that if and when i sell my current iphone for the new one this might sound stupid but do it leave the sim card in and just restore the phone? or do i take it out and (obviously) restore the phone? if you could let me know that would be great. thanks.

Restore and remove. Or buy new phone, activate new phone, old sim card is now useless (after a restore).
