I use freecycle (brilliant service) to get rid of everything - that is give - things I can longer use, but somebody might.
My previous phone lasted 6 years till it croaked. I would have kept my 3GS for years (it is the best part of a year over replacement date) - except - if you read - you will see it is broken!! So since I cannot get it fixed - I have to buy another.
Sad but true. So the question is what not whether.
