Introduction

First let's define a smartphone,

A smartphone is a phone with at least 2 processors:

one where runs the operating system(like Android,GNU/Linux etc...), it is usually called the Application processor
another that interface with the GSM network(for instance it reads the sim card,interface with the GSM tower etc...). It is usually called the baseband.

Historically both processors talked to each other trough AT commands(also known as Hayes command set.

While freedom is possible on the GSM processor too,we will focus on freedom on the Application processor(because it's illegal to run modified GSM processors on carrier networks and also very dangerous)
