history of phones (innovation and change)

This week I have been learning about phones for innovation and change I found this task a little hard because it was hard to make the timeline. I also found finding information hard because there were so much information so I did not know which information to use  I think I need to work on getting more information and learning how to paraphrase which is putting the information into my own words. I would like to know ho many people have a phone and how often they use it, I would also like to know how many times the phone has been changed since it's invention. How many phones have you ever had and what would you like to know from me. Comment below.
