Yeah i agree with the above. Doing a reset requires holding the home button and the sleep/wake button down until the apple logo comes up. If the logo doesn't come up after atleast 10 seconds you definitly should bring it to where you bought if from. Hopefully it does work then run a restore.
Well before I could write a response you had it fixed. So for the battery it is okay for you to plug it in when it is half full. Try and not leave it plugged in once it is fully charged. Go ahead and do a search of the forum for battery. There is a great thread on good practices. I would paste a link but as usual I'm on the iPhone with no pasteing
