Update:

After 4 weeks, several unproductive calls to Nokia Ireland Customer Care (based in Scotland), and still no Nokia Ireland representative calling to my home to collect my defective Nokia 770 (as continually promised), I got very very mad. I Every time I rang it was like I was reporting my 770's screen problem to them anew. have never come across such a disfunctional customer care department! At one point I made an official complaint (10 days later and Nokia's complaints Dept have not gotten back to me).

Finally, after extracting a promise from a customer care agent that a Manger would would personally resolve the problem, Nokia's service agents in Dublin phoned me the following day. The day after that they arrived at my front door and swapped my defective 770 for a new 770 - which is mine to keep.

I guess good things do come to those who wait, and wait, and wait, and wait.....
