Request for review: GSM phone hardware introduction

[emersonv6]

Hi,

First,  congratulations for the project, it got my attention from the
first day I heard about it. At the moment I'm trying to get one of the
C123s so as soon as possible I'd like to start contributing in some area.

I'm totally agree with the full document but found some minor
gramatical mistakes:

page 7, chapter 5 Synchronization and Clocking, first paragraph:
	- ha
	- means meant
page 9, section 6.3 Dual-SIM and Triple-SIM phones, last paragraph:
	- baesband

page 10,
	paragraph 7:
	- kidn

keep the great work,

emersonv6
