Thanks for spending some time with our project and for pre-ordering!
At the moment we do not have plans to open source the OS however it is totally something we would be open to considering and talking over with our CTO and software team about how that might work.
Yes the sunsetting of 2G network is a concern, even more so in some other countries than the US, but so far we’ve been assured that TMobile will be supporting 2G for the foreseeable future. We are exploring a more future proof version of the Light Phone as well that would work on 3G, 4G, as well as other potential options especially for other countries that either only use CDMA or have already begun sunsetting 2G, but we are very focused on finalizing this Light Phone and getting it into the hands of our earliest supporters. We want to do everything we can to support and be fair to our earliest adopters going forward.
Feel free to email Kai and I anytime with more questions at firstname.lastname@example.org, it goes straight to both of us and sometimes it is hard to check Medium often and I wouldn’t want your questions to go unanswered. I hope that I was able to answer your questions and am looking forward to sharing the Light Phone with you this fall.
All the best,
