I got the iphone so I didn't need a mp3 player and phone. So this is a little upsetting unless it's just my phone. Also on the topic of cords. I need a longer wall charger. Is it really necessary to get an apple brand. What about a 3rd party brand or one off eBay?also would buyin a higher voltage one or an iPad one charge it any faster?
