In my opinion, the iPhone is the best cell phone since it has a very good camera and it is very nice, everyone wants an iPhone, I have tried other cell phones and I have liked none more than the iPhone, it clearly has some cons such as the battery when it wears out it doesn't last long or sometimes the space isn't enough, but other than that it's a very good cell phone.
