It'd be easier to fix a broken charger, because to replace the battery you'll need to send your phone to apple for servicing. If you have a spare USB to iPod/iPhone cable lying around (all the previous apple iDevices, including iPad, use the same connector), you can connect your iPhone to a computer and see if it charges. Hope that helps :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
