I would like to buy an iPhone but do not really care for having the phone feature, people told me iPod touch 4 will be good. But when i entered on apple's site and went to the iPod touch spec, there was no retina display feature written, i suppose this means that the iPod does not have retina display, and many people say there is difference in ram and so on... So please i want someone to tell me even the smallest difference between the iPhone 4 and the iPod Touch 4. Waiting for your answers and thanks in advance.
