How to set up iCloud on my iPhone?

I bought an iPhone 4 from a cash converter site.

I want to set up iCloud. I have a laptop.

I've downloaded iCloud onto my laptop.

I have no idea what to do next to set up an iCloud account.

Can you give me a step by step as to how to set up an account?

Go into the settings app on your phone then on the left choose icloud from the links it will walk you through once you choose to turn it on. It will set up your account with the same name as your apple log in except with a different file extension.

Once you have done that it's up and running.
