你还是先了解了它的功能再问我吧。iPhone有三个核心功能，就是优秀的手机、最好的iPod，还有手机所能提供的最好的网络功能。先说iPod，虽然和iPod相似，但是它有更强大的音频、视频和照片管理功能。容量也特别大，一款是4G，还有一款是8G。你也知道iPod和一般的MP3是两码事，你的手机不会只能听音乐吧？

Before you ask me, you should understand the functions. The iPhone has three core functions: it's an excellent cell phone, the best iPod, and the best online functionality that a mobile phone can provide. Let's talk about the iPod first. Although it looks a lot like the iPod, it has even better sound, video and photo management functions. It has a really big capacity-- there's an 4G model, and an 8G model. You know that the iPod is really different from a normal MP3 player. Is it possible that your phone can only play music?
