Any Advice?

So I found an iPhone and don't know if its 3G or 3GS, the iOS version or if its jailbroken. The phone is dead and wont charge. I connected it to a USB plug outlet and to a pc and the phone doesn't respond to it. Should I go to Apple or a cell phone repair shop? If I go to Apple and find out its jailbroken can they confiscate it?

 

I found it yesterday and its been charging the whole day. Tried the 45 second thing but this screen just keeps coming back (http://www.redmondpie.com/wp-content/uploads/2010/03/ipaddeadbattery.jpg -> i know thats an ipad but its the same screen)

 

Can I get some help here? I just wanted to know is the problem a serious hardware issue or a simple replacement of the USB connector?
