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!"
I totally forgot about E-mobile. Right now they are operating as an MNVO on docomo's network, so obviously they're currently on 1900/2100. I seem to recall that their roadmap included voice service on docomo after thier 1700 HSDPA network goes live next year, so at the least any handset they use hast to be dual band UMTS/HSDPA...I think.
E-mobile's network will be 1700/2100, and for some reason I thought T-Mo's network was going to be 1700/1900, which would make the handset's incompatible...But maybe I'm wrong about T-Mo's plans. According to Wikipedia's UMTS page, it seems like their network will be 1700/2100 as well.
That's good for me...at least it will be if Emobile extends their service to my small town...
