I still have the 3310 Nokia. The battery works just fine but now the phone is dead, afterall it is around 9 years old with me.
Thinking of repairing it if possible and use it again. The thing was a legend.
I had a Samsung C100, which I threw against wall and kicked it, tossed it towards friends and other similar harsh use and it works to date! Just takes time for signals, otherwise is just fine!
