Just downloaded update for my iphone and now it wont turn back on and all it shows on the screen is the usb plug with an arrow pointed at itunes

what do i do

Why did you disconnect it when it showed that screen? That is just one step in the update process. You need to complete the update; that is what that screen says. Just plug it in and let it finish. If it doesn't see this article: http://support.apple.com/kb/HT1808
