I've been using it for up to 6 hours a day for about a week and the reception has been good.
We have travelled down from Valencia and are currently in the small seaside town of Calahonda near Murcia on the Costa Tropical. Signal strength has been high.
I also purchasedf a new phone from Carrefour for 19 euros including a sim with 10Euros on it. This is cheaper to use to phone home than a telefonica phone card.

I would highly recommend it on my experiences so far.

I am using a Yoigo SIM in an (opened) Vodafone PCMCIA 3G/GPRS module. I am browsing right now in Port Vell Barcelona and downloading an entire newspaper at the same time. My Net Meter is showing peak of 55kB/s with up to 30 seconds at a time of near total dropout. Last night, I had excellent Skype calls over an hour or so. I also have Telefonica WiFi access which is good but pricey (€12 per 24 hours seemingly unlimited as I am a fairly heavy user - 250MB to 1GB in a 24 hour period. However, Telefonica seems to have a Port 25 block making it impossible to send POP3 mail. My AOL and Hotmail (using Outlook Connector) accounts sort of work but at a snail's pace. My guess is that it is deliberate because as soon as I connect via Yoigo the problem goes so it seems unlikely to be a problem with my configuration or system.

The problem with Yoigo is that in many places (I have travelled from Almeria province up to Barcelona, along the coast in a boat) there seems to be no 3G or EDGE service available so the connection can be almost unusably slow. Outlook has trouble with those speeds and I have to use Airmail 3 which is designed for ultra-low bandwidth connections.

Can't answer your question about the iPhone, tho' ;)
