Basically it needed a reset... so that'd be all the batteries out and leave it for quite a while if I recall.

Wayhay - you were right indeed after all that. Left the battery out for an hour or more and at least now the phone's live again if nothing else - still not working for calls as such but happy to have at least got this far as that's bound to save me some time/hassles when talking to the service guys on Monday - so ta for that suggestion. Wouldn't have thought of waiting quite so long perhaps on it which was why it wasn't working last few times I tried it.
