just insert it? And I just wanted to add question: what Iphone 16gb or 32gb is the best that will work good on youtube video and porn sites.

well actually it depends on the iphone as in the u.s. these iphones are att locked and therefore need to be unlocked which u can do urself
but there is officially unlocked versions of the iphone sold overseas with a full apple waranty and sometimes u can find here these phones are not likely to be scams since some countries such as taiwan mandates that ll phones have to be unlocked or unlocked upon request
