If you buy an iPhone from o2, you either need to buy it outright or with an airtime deal @MichaeliPhone.
Log in to your account, and see if there is an option to upgrade and see what deals o2 can offer you.
Or visit your local o2 shop and ask for help there.
If you wanted to get the phone without changing your current deal then you would need to look elsewhere - Apple offer payment plans, but other retailers also sell the phone.
