Fairphone

I've been checking the page linked above every day hoping the bigger spec version of the FP5 (more ram+storage) with /e/os preinstalled will be back in stock, but for the past month or month and a half its remained out of stock.

I would like to make the switch as soon as possible, but I'm not sure when it will be back in stock. Just so I have a complete and well-informed picture of my options, would it be possible to have a tl;dr of the comparison between the preinstalled version and the stock version where I put /e/os on it myself? I'm talking about stuff like warranty voiding, issues with the install process, etc...

Thanks in advance!

p.s. Anyone have any idea when it will be back in stock? :p
