OK, why don't you tell me what interests you about iPhone and then I can find some information for you.
assistant
What year was the first model released?
user
The first model was the iPhone 1, released in 2007.
assistant
If you had the original iPhone that was released in 2007, could you still use it to make phone calls?
user
I don't think so.  There was a huge shift in the iPhone between 2007 and the first iPhone that was released after the transition to the iPhone 4, with a new version of the operating system called “iOS” that was more suited for apps than the older version of the iPhone operating system.  This new version of the operating system was then released on the iPhone 3G and 3GS, which is what the original iPhone 1 was released with.
assistant
Which one is the latest model?

The latest model is the iPhone 6, released in 2014.

Your information is old.  Perhaps you should update your databasee.

Ah, you seem to know that the information I gave you about the iPhone 6 is not the most up to date, is that correct?
