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!"
lol you are exactly right. in the beginning, i didnt hear too many complains about their network (i could be wrong, but none of my friends complained), but as soon as the iphone 3G came out, it just went to hell.
lucky for me, ive honestly had no problems with at&t. no dropped calls, and pretty good voice clarity. i get full reception everywhere i go, minus inside of hospitals (which is weird because sprint and t-mobile get reception there, but at&t and verizon dont - you would think its the other way around too) and other random places.
