I havea iphone does it use android

No it uses iOS.

Android is by google and is Apples competitor.

Not unless you install it yourself:

I wouldn't recommend it.

Nope, your iPhone doesn't use Android.

Your iPhone is made by Apple and it uses the iOS operating system.iOS is exclusively made by Apple, for Apple.
The most current version of iOS is iOS 6. If you're curious how the "iOS" name came about, OS is a universal acroynm which means Operating System, so when you think of i + Phone = iPhone, i + OS = iOS makes sense.

Android, on the other hand, is an OS developed by Google, and is an "open source" OS, meaning any company (such as Samsung and HTC) can use the code for free and tweak it to their liking/to suit their device.
The most current version of Android is 4.1 Jelly Bean. Unlike iOS, Android updates are usually very slow in reaching most smartphones/tablets. New updates are often used as a selling point for new devices. Only 1.8% of Android devices run Jelly Bean as of the start of this month.
Interestingly, almost every major OS update by Android has been named after a sweet food of every letter of the alphabet, starting with Cupcake inn 2009 --> Donut --> Eclair etc. All the way to 2012's Jelly Bean.

Don't do it, or you may damage your ipHone.

but you can also try to buy a clone iphone with android system.
