Do I need and adapter AND a converter in Ireland?

I'm traveling to Ireland next week, and plan on taking my iPhone, flat iron, and camera. Will I need both adapter and converter, or just the adapter? I recently bought an adapter set, but I was worried I might need the converter too. Any help is greatly appreciated!

Yes. You will as Ireland is a foreign country.

OiPhone? What magic is dis?

Electronics like iPhones, iPods and laptops are all dual voltage. All you need for them is the adaptor. However, the iron (by which I assume you mean a device for the hair) needs a converter or you'll blow all the circuits.
