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!"
The existing outdated GPRS-compatible network in Spain is very easily adaptable to EDGE (primarily because there are very slight differences between the two of them).
Telefonica has been waiting for iPhone 3G, which is the reason of the delay. In a country where almost every single cellphone is already 3G or HSDPA, it would be nonsense to launch a product that works with old networks.
