What phones will be like in 100 years ?

There's many types of phones in this world. Apple and Samsung are one of the most popular brand. Let's talk about how iPhone will be like in 100 years ! There's iPhone 3Gs, iPhone 4s, iPhone 5c and iPhone 5s. It's getting longer and longer ! What if... There's iPhone 99? Will it be like a kilometre long?  If Apple is producting different kinds of iPhone each year, there may be a chance to have iPhone 99! 😅 I'm pretty excited about it anyway ! Even though I'm too old for that during that age. Maybe iPhone 99 is a tiny little phone? Or a huge long phone? Who knows? 😁
