A lot of the information on this page is outdated. For instance FSO+SHR doesn't exist anymore : it was repurposed to support other phones with another stack. The Openmoko smartphones aren't supported by any distribution anymore, and it would be difficult to do it due to the lack of ARMv4 support: Debian stopped support for ARMv4, and no FSDG distributions support ARMv4. The Nexus one, and Nexus S were dropped from Replicant because (1) upstream dropped them (2) serious privacy/security issues were discovered: the modem could potentially take control of the complete phone. The Palm pre wasn't supported by upstream. The code to make the modem work was lost, then Replicant asked its author a copy for historic archival purpose and it was found again. But then the modem stack depended on FSO which is unmaintained since years and people moved on. It also has no upstream support in Linux, though it's CPU is armv7. so it could be supported by GNU/Linux distros like Parabola.

Possible Free SmartPhones target comparison

Introduction

A lot of the information on this page is outdated. For instance FSO+SHR doesn't exist anymore : it was repurposed to support other phones with another stack. The Openmoko smartphones aren't supported by any distribution anymore, and it would be difficult to do it due to the lack of ARMv4 support: Debian stopped support for ARMv4, and no FSDG distributions support ARMv4. The Nexus one, and Nexus S were dropped from Replicant because (1) upstream dropped them (2) serious privacy/security issues were discovered: the modem could potentially take control of the complete phone. The Palm pre wasn't supported by upstream. The code to make the modem work was lost, then Replicant asked its author a copy for historic archival purpose and it was found again. But then the modem stack depended on FSO which is unmaintained since years and people moved on. It also has no upstream support in Linux, though it's CPU is armv7. so it could be supported by GNU/Linux distros like Parabola.
