Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
I Don't get the point... Telefonica is SPAIN only, and there is Vodafone in spain as well... Vodafon already is in UK/France/Spain/Germany... so why would they share anything with Telefonica? and If I travel somewhere I ALWAYS have coverage because all the carriers here have Roaming contracts... the only cool thing would be if i can place calls between countries and NOT pay roaming charges...
Telefonica own O2 in the U.K, so the sharing extends to the O2 network in the U.K., I would imagine it's the case in the other countries as well.
