3.3.0.16 didn't break calls for me. I still have issues with 3G and overall network reception, but it might be hardware, and the update didn't change it.

Unrelated: Havoc, a Wayland terminal emulator, has been ported to SFOS over the past few days by @ii8. It fixes all rendering issues previous native terminals have with ncurses apps, nano, limited colours, or stuck scrolling (I had that in Toeterm). Text selection and scrolling are not mutually exclusive thanks to multitouch support. It has no virtual keyboard, so it is not ideal for other devices, but with the Pro¹ I believe the experience is really close to that of a desktop terminal emulator.
