An iPod or an iPhone 4?
The similarities between iPod fourth generation and Apple famous iPhone 4 are many. Since both of them have the same 960×640 resolution Retina Display, twin low performance cameras, and the same possible storage of, 16, 32 and respectively 64 GB, and the most important a similar design, there is no major difference between the two of them. Buy an iPod touch 4th generation if you want to focus on good quality music, enough storage and almost the same features as an iPhone 4.
