Which comes first?

I wish I could help you out with this. But as far as I know they are one and the same if not i hope someone will correct me if I am wrong on this.

The first one is invented by Motorola in 1983 and the price of it is about 3,995 dollors.It is called DynaTac 8000X.At present,cell phone has devided into smart phone and feature phone.Under normal circumstance,smart phone is better than feature phone,but the feature phone is stability

I believe their the same but not for sure. Most people call it cell phone but others cal ltheir phone a mobile phone so could go either way. Hope you find out the right words to use.

The two terms mean the same thing. The cell phone term comes from the way the "mobility" is technically achieved. Space is broken into so called cells. I'm not going to go into details, but basically, when a person is moving from a "cell" to another and he/she is having a mobile conversation, all the information about the call from the cell he/she exited is transferred to the controller of the new cell. This way, the conversation may go on when moving from "cell" to "cell". Therefore, that's why they are called cell phones. Cell phone is more technical if you start to analyze it, mobile phone is more familiar language.

Cell phone and mobile is the same, they mean the same. I'm gonna come with a tip for you. Please make your discussions more advanced :) You only had one line here with two questions.
