My sons think its endlessly funny that I still have the old Blackberry that I bought off my youngest son when he upgraded his some years back.
It still works perfectly, I am not on facebook, twitter, or any of those. I turned the email off because it kept bleeping to tell me things I didn't need to know like the socks I ordered have been dispatched. I don't have apps
I can see it easily it lasting a few more years yet. It has already outlasted several of my son's Iphones and I pay £10 a month for unlimited texts and 500 minutes of calls
What do you have?
