Serial numberis on back. Google it

By the size look online the 4 doesn't have Siri and its small pretty heavy the 5 is slimmer and taller.

Find out the serial number printed on the back and Google it. You'll find which iPhone you're having.

  • People that buy iphones don't know anything about technology did you know that? Like my friend just brought iphone and I asked him if it has 4g late he said what's that? Then I asked how fast is the processor like 1.2 dual people buy them because its more mainstream and because their friends have iPhones Samsung is way better based on specs and technology the iPhone 4s and 4 processors are very slow
  • My iPhone 4s (13.50GB capacity) has 0 bytes available which I know is odd? My sister has the exact same phone and storage capacity as I do, but carries way more photos and apps, and still has so much space available (about 5.50GB). I've stripped my phone almost of every unnecessary app, photo, video, song, etc., and I still run out of space extremely fast. Can anyone tell me what's wrong or what I can do to fix it?
  • IPhone or Android? I don't know which one to choose I'm not sure which device I want to go with. I've been hearing very bad things about iPhone. It's battery not being able to be removed. And it's small screen size. Android with it's bigger screen, and sleek design. Help me choose guys. I want everyone to give me your personal opinion on both the devices.
  • IPhone 6s plus or 7 plus. I know the prices and what they do. But what I wanted to know is Did the 7 fix the home button problem? That s my main worry. I use my phone to text, check facebook, candy crush, look up info, and take the odd picture… Will I notice the difference between the two phones to be willing to pay more for the 7? Hoping for opinions for 6s plus and 7 plus from past of present owners.
