No reception, ever, South of C470 and to the West of Ken Caryl exit including the Valley and Deer Creek Rd. Verizon was just as bad as T-Mobile.

Love the iPhone, but reception has degraded in recent weeks. AT&T says my nearby tower is broken and they don't know why it isn't fixed yet. Apple says AT&T is too busy in Vancouver to fix Denver. Verizon has coverage but Storm evidently sucks. Maybe class action suit (breach of contract) would help, like another poster suggested. ~D

In the past 6-9 months the reception has gone from bad to none. Dropped calls, no bars in areas a couple of years ago I did have.

Been with AT&T for years, this summer service went really bad, customer care says nothing meaningful, rumor has it they are upgrading system but no one can tell when this poor service will end. Switching to Verizon in October 09 along with all my neighbors!

No reception with AT&T on Hwy. 86 from Franktown Intersection to Elizabeth. Also there is no reception in any neighborhood near this road.

Anywhere past mile marker 7, and there is no reception from any cell service. You would think that someone would put a tower up since this is a huge tourist area throughout the entire year. I would hate to have car trouble on this highway because you are out of luck when it comes to service.

I would recommend NOT buying an iPhone because of the poor (as in NO SERVICE at times) AT&T signal. What good is a phone if you cannot make or receive calls??

Reception getting worse and worse, not only in my house and home office but around the Denver area. I do not even get EDGE 90% of the time let alone 3G service. Drop calls no voice mail etc... Its a joke at this point and calling ATT does nothing however I have started to call every week. I have 6 min of talk time on my Aug bill.. on the flip side I have a T-Mobile phone as well and perfect service full bars no dropped calls...

New commissary and BX Peterson AFB No reception phone tries to find signal but just drains the battery.

AT&T is horrible. My boyfriend just got an iphone and it drops almost every call. It will actually say "good-bye" in the middle of me leaving a message and then hangs up on me. The phone is cool and long as you don't actually want to make calls on it- haha. Right now he is trying to get his iphone replaced because the battery stopped working and they actually have to take the phone apart to replace the battery. What were they thinking when they designed the phone???????
