My iphone 4 won't turn on? - 3

So i updated the settings and after it finished it turned off and now i can't make it start again!

What do i do? The device is new by the way

Try taking the battery out and putting it in again, make sure it's fully charged also.

Try recharging the battary or replacing it

Lol at all these people that are saying to remove and replace the battery -that may work but you can't just remove the battery from the iPhone without taking the whole thing apart

- you better send the phone to a repair center if you don't want to mess it up yourself

and thank Apple for making their products so proprietary and have non removable/upgradable hardware… Cause that's user friendly >_>
