Do electronic devices work as normal in the vacuum of space?

Lets say, an astronaut conducting a space walk pulled out his iPhone without any casing, protection etc would it work as normal?

As I'm typing this I'm feeling stupid as I've realised it would just freeze wouldn't it?

If it did have protective casing would it work as normal?

Actually the broblem with most modern electronics in vacuum is overheating. Since in vacuum there is no medium to dissipate heat effectively and it will cause overheating without sophisticated cooling mechanisms (which an iPhone doesn't have).
