I used the Philips website, not a phone number. Maybe I'll get the "undeliverable" message in a week or so too! ;)

I just had a long chat today with the people at letsautomate.com, and they have been in touch with Philips. Apparently, they had a "bad batch" of network cards, so they are sending out replacement wireless network cards which should resolve this problem. Letsautomate are hoping to get a good supply so they can cover any customers with problems. I'd suggest that anyone who is suffering contacts the place they bought their iPronto from. Hopefully all retailers will be aware of this by now.
