I got an iPhone 3 and I can't download any thing because I need IOS 7 or higher?

So I got an iPhone 3 and I can't download any thing because I need IOS 7 or higher?

IPhone 3 is 7 years old. Apple updates as soon as possible, so that they make more money. Best way is to use it as an iPod.

The only thing iPhone 3 is good for is an MP3 player. It's too old to do anything else useful.

Well, you should have done a bit of research first. The iPhone 3G came out almost 8 years ago. Apple stopped providing software updates nearly 6 years ago.
So, it is very obsolete.

There isn't anything that you can do about it. You'll have to get at least an iPhone 4 or newer.
