5.  INTRODUCTION
Smartphone are mobile devices that do a lot more than
just make calls and send texts. They have cameras; they
play music & videos; they send and receive email; they
browse the web; they have GPS satellite navigation.
They also have QWERTY keyboards (real, virtual
onscreen or both) and perhaps most important of all,
they run apps.

6. HISTORY
1) Motorola introduced some of the first cell phones to the public during the
1980s. These cell phones were completely unlike the cell phones of today
since they were not at all compact nor by any means cost effective. Some of
these cell phones cost as much as $4,000, and weighed over 2 pounds!
2) The first smartphone was developed by IBM and BellSouth, which came out
to the public in 1993. Although basic compared to today’s standards
“Simon” had a touch screen that was capable of accessing email and
sending faxes

7. OPERATING SYSTEMS
