Sally, from what I understand, most things are made for both electric currents now. I know my Droid, tablet and straight iron are both currents. (not sure about an iphone) You can usually find out if it an item is adaptable by looking in the manual if you still have it.
My blowdryer has a switch to change from current to current.
What you might need is one of those collections of plug adapters so you can plug it in ;)
Here is a set of those at Staples for $12.99
