As things stand today, we expect a fully functional prototype in August
https://www.pine64.org/2019/06/06/june-2019-news-pinephone-p...There are lots of patches floating around, that you can apply to the mainline linux tree, to get CPU DVFS, thermal management, to improve I2S support, etc. Suspend to RAM is nowhere to be seen, leaving you with always ON SoC, which will drain the battery in half a day doing nothing.
It's all fixable, but let's not pretend A64 has fully fleshed out HW support in the mainline Linux kernel.
OTOH, there's a great potential, because Quectel EC25 broadband module also runs Linux and has some potential for being hackable:

So there's definitely a lot of fun to be had with the future PinePhone. You'll be able to log in to your broadband module and perhaps modify it:

we also settled on the number, and the implementation of, privacy switches on the phone – there will be 4 switches in total: for the i) BT/Wifi module, ii) the modem, iii) cameras (front/back) and iv) lastly for the microphone.
and right on the pinephone page it says it has this chip:https://www.quectel.com/product/eg25g.htm
Key Benefits
