How to tell how long you've had your iphone?

4S

Remember when you first bought it, dumbshit

Shouldn't you know that?

I'm not really sure on how to find out the information on your phone, though. Best of luck: D

Only an iPhone owner could be that stupid… LOL

If your the original owner, then just call your phone carrier ask them when your phone was activated. They should be able to tell you when it was purchased or activated. If you are not the first owner of the iphone 4s, then just call your carrier and tell them you forgot the date you had it activated and would like to know. Normally this date is most likely to be the first day you had your phone serviced. Hope that helps?

EDIT:

if you want to know how long your phone has been in use even before you purchased it, i'm afraid no one can help you there.lol

Umm for all those people up there ^^^^^^^ yea some people want to know how long they have hade there phone. I have had my 3g for 4 years had my 4 for 2 years 4s for 1 year and 6+ for 3 months but how do you find that information out you google iPhone sercurity then type in your serial number and it tells you how long you have had it eg 7months 4 years.

Maybe since I don't have to buy a new phone every two years because iPhones last a long time I would remember like you do
