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!"
All the information on pricing out there in the past day is bunk. From Sprint's own website, an Airave base station with let *ANYONE* with a Sprint phone get on the base station. If you want unlimited calling, however, you must have the unlimited Airave plan which is $15 OR a Simply Everything plan.
If you don't believe me, read it here:

(Oh and notice that a ongoing call will not hop from Sprint's towers to a base station and vise-versa. So no one driving by your house is going to accidentally end up on your bandwidth.)
It's looking like no one really has a good femtocell solution yet. If it can't do a handoff, it's clearly not acting like a mini cell tower. I've been using T-Mobile's Hotspot @ Home for over a year now and the big drawback to theirs is that you have to have one of a precious few UMA-enabled devices.
