Introduction
First let's define a smartphone,
A smartphone[1] 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 a serial port, with 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)

- ↑ Nokia Updates are capable of flashing the modem firmware, in fact unpacking the PR 1.3(The version of the nokia Update)update with 0xFFFF shows that the modem firmware was flashed,also some modem properties changed between PR 1.2(The version of the nokia Update) and PR 1.3(The version of the nokia Update)

Jan 14 20:58:10 <mrmoku> GNUtoo|laptop: btw. what about xrandr and rotation on n900?
Jan 14 20:58:28 <GNUtoo|laptop> do we really need that?
Jan 14 20:58:44 <GNUtoo|laptop> I mean we would have to modify xf86-video-omapfb
Jan 14 20:58:49 <GNUtoo|laptop> and write the code ourselves
Jan 14 20:59:07 <GNUtoo|laptop> the rotation driver of nokia depends on non-free 3d
