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!"
As I have been looking into this, I've done some research. I found a website that listst all phones that are compatible with this dual-sim adapter (They call it a "non-cut" version). Haven't bought it yet as I'm looking for other suppliers as well, maybe I can find it cheaper somewehere. Anyway, the link is: http://www.dual-sim.eu/overview_ii.php .
Kind regards,
