i've reached a point where i don't want it to be a phone. they just turned off 3g in my country so my nokia 3310 from 2017 loses a lot of functionality when i lose it's browser with an rss reader that was so very handy.

wifi and bt to link to your network or phone to access data would be excellent. a shame there'd be no avantgo for mobile offline web which i absolutely loved on palmos. sync before you leave the house and i'd have news downloaded for the day to keep the boredom away.

with just those 2 protocol it could link to devices and services for many years without been dependent on special hardware to talk to the phone networks.
