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!"
Honestly, not all of us live in a major metropolitan area. I live less than 20 miles outside of a major city area, and the mountains, redwoods trees, and tons of other things prevent us from getting good cell coverage. We have our own towers in the area, but even then, we will go from 2 to 3 bars to nothing, and then back again while driving. Wireless antenna boosters help beat those dead spots. Also for people who live in more rural areas, where the relay towers are very far apart, can also benefit from such a thing.
Products like this are not new. However it has become a new thing to do this wirelessly, so you phone _just works_ and you don't need to plug in and unplug an external antenna jack.
I am curious also if they have done any contracts with any major manufacturers.
