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!"
Benefits:
1 - Holds up to 500 contacts and 5 numbers for each
2 - Easy dialing hit * and then the talk button
3 - If you lose your telephone, the numbers are still there
4 - Very easy to upload and manage numbers
At $5.00 per month it is worth every penny.
