The Nokia 8810 4G has just been announced at Mobile World Congress 2018. Bringing back classics has become a speciality of Nokia after the success of the 3310 last Mobile World Congress, so the refresh of the 'banana phone' shouldn't come as any surprise. It does look like Nokia has learned from the 3310 though, with the new 8110 packing 4G and promising a better app experience than last year's offering. The phone will also stay alive for 21-days on a single charge and yes, it's available in yellow too
