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!"
"the X1 will apparently be launching in mid-September. Of course, we'll still have to wait to hear from Sony Ericsson to know for sure"
There have been many instances where SE has told a release date for sept 2008... Even if you ask their executives they will answer the same... Few week after X1 was announced (few months back), I got the same reply from SE at a Mobile Expo...
Plus many insiders have also confirmed this...
So till now, according to SE, X1 is indeed to be launched in september and no for SE to confirm this... They need to confirm if they delay it...
