I have a Nokia N95 8GB with Symbian 9.2. I'm curious to try a different OS on it, and since Linux is my favorite and the OS I plan to switch to I'd like to try it on my phone as well.

I seen several versions of Linux for mobile (afaik N95 is ARM based). I read about Linux distros for ARM but couldn't find any downloads. My preferred distro is OpenSUSE / SUSE which I use for my PC.

I don't wish to try anything risky such as hacking my phone or reinstalling the main OS at this time, so I'm looking for versions of Linux that are installable like normal Symbian applications, if any exist.

I know it's not much help, but there is a program for windows mobile that acts as a bootloader (similar to the bannerbomb exploit for the nintendo Wii if you're familiar with it) that'll reboot the phone and run linux (android) installed on an SD card. If you don't like it, uninstall the application and remove the SD card.

Maybe something similar exists for symbian?

Indeed, it would nice to have linux running on the N95 as well similar variants like the Nokia E90!
