After 5 long years of service, our current mobile phones are still surprisingly serving us well. My wife and I have Sony Ericcson brand mobile phones – Mine is a walkman phone W810, and the other one is a K800i. They both still work for text and calls, the only issue we have with it is its lower than usual battery life, but they are still usable.
I could go so far as calling my phone a Super phone!
Lately however, we are contemplating on getting a newer phone with touch screen interface and internet capability. The new phone will work as an internet browser and a phone so we can use it for our online work.
