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)

Details available here |
|
|
Depend on non-free drivers | No | No(TODO: check if GTA01's gps is supported by proprietary software named glin) | Yes 3D driver is required, and no decent free one exist for phones. | No |
Non-free firmwares Policy | ? | Not shipped(not redistributable) but promoted,not needed in case of the openmoko freerunner,linux-libre not used | Non free firmwares Shipped | linux-libre not used,a page details which are needed for what but doesn't tell how to install them(altough it's obvious for the experienced user) |
Checked for freedom | ??? | No but its developpers are against proprietary software inclusion | contains non-free software | No:The main low-level developper supposed that the sources he forked were, he replaced non-free not-included parts and looks for help on this point. |
