I accidently pluged my iPhones audio jack into a plug that goes into a wall outlet?

The plug that's on head phones that goes into your iPhone. Well this one did not go to head phones it went into the wall now my phone won't turn on.

I'm pretty sure I'm safe in saying that this iPhone is going to need a trip to an "authorized repair depot" or to be replaced. Sorry, things expecting to output power don't like inputting power very much. In more technical terms, I believe that one or more transistors on a chip or the board itself may have been exposed to what is called reverse breakdown voltage. If it is exceeded by too much voltage / current or time, the transistor will be destroyed and nothing short of board level replacement will fix it.

Sorry to be the bearer of bad news.
