TMobile is kicking old Android phones off their network in January because vendors have abandoned the hardware and they no longer get security updates. Android's model of forcing you to buy new hardware every few years to get security updates is broken. https://www.tmonews.com/2020/12/t-mobile-will-no-longer-support-devices-january/
@kyle is Apple any different? (Honest question, I don't watch their ecosystem closely.)
@isagalaev Any different from what?
@isagalaev Apple tends to support iPhones with software updates for *much* longer.
@kyle one of the phones in that news is a 6-year Sony Xperia. I think it's considered pretty old. (Which in my view is still not the reason for T-Mobile to selectively disable devices from connecting, it's totally lame and hostile.)
