In reply to Martin Hore:
You may have friends who have upgraded and still have an old one in a drawer? A phone with a near-dead non-replaceable battery would be pretty useless as a phone, but might work for you?
In fact if you're in Edinburgh, I'll give you an old Moto Defy. Edit: Scratch that, the Defy is too old to run the app.
