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!"
It just means that they'll allow devices with ESN's that they didn't sell to be added to their network.
Personally, I'm not just "not a verizon fan", I'm an anti-verizon fan... so this isn't directly important to me. The way it will matter to me is the effect it will have on the market. Sprint is already on its way to opening up its network (wasn't there a settlement a few weeks back?). So, two of the big 4 US carriers are now opening up to some extent.
How will this pressure the small CDMA carriers (especially MetroPCS)? How will this pressure the GSM carriers here (T-Mobile and AT&T being the big two)? If MetroPCS, T-Mobile, and AT&T become more open, then that's "all good" from my perspective.
