I may have, at times, 5 bars, then the signal just disappears to 1 or none! AT&T claims I have very good coverage in my area but even if I walk around the neighborhood it is difficult to use the phone. Come on AT&T- this is a large city! Why can't I make a phone call??

I'm in the top floor of one of the taller buildings in d / t and have little to no coverage in my office. My phone will show 4 bars or more when I go to dial a number but as soon as the call connects it drops down to 1 bar. If the call doesn't get dropped then I can hear 1 out of every 4 words from the person on the other end. Pretty horrible coverage in downtown Denver for the most part.

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

Everyone in the world I meet Im going to tell about ATTs poor service in the denver area and they in turn will tell others, Half the calls I make I get 1 bar plus static then disconected. ATT SUCKS, Im telling everyone. Customer service says its my fault... ... ... ...

It's getting worse over time. I love my iPhone, I just can't use it as a phone when at home.

I very happy with the iPhone but I VERY UNHAPPY with AT&T voice quality and signal coverage. I often cannot make a call in or around my home! Don't buy an iPhone if you need to use the phone.

This is my second post. My ATT cell phone service is poor to none. I've spoken to ATT Customer service each week for the three weeks that I've been in Denver. Although they are quite pleasant about the whole thing and assure me the problems with dropped calls, "call not allowed", poor reception have all been corrected, they have not. I am now considering the "breach of contract" argument, since they have told me I am within a mile of a tower yet cannot use my cell phone 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...

My reception has steadily degraded over time. When we first got the iPhone, reception was fine - not perfect at home - but solid and useable. I had very few dropped calls at home, but now service is absolutely horrible! I upgraded the software to 3.0 (3GS software version) but kept older iPhone. At first, there wasn't any change, then slowly but surely over time service has degraded where I can't get calls at home. Downtown, 3G service is a joke. In a major metropolitan area, the fact that I can't get perfect service most of the time is pathetic. I am really frustrated with AT&T. I have a hard time believing this is an Apple problem because I have used Apple products for years and have consistently had good to excellent experiences. I know that Apple is not perfect, but the track record is good and AT&T has a history of being obnoxious to customers. I really hope this gets fixed because I really like the iPhone.

One minute good reception, the next nothing. Bounces all over the place.

I have very poor AT&T signal strength at 14th and Cook street. Failed calls, dropped calls, and very poor quality when a call is completed. I love the iPhone device itself but it is supposed to be a PHONE! I want to talk on it! I had better coverage (far better) when I was in little towns in the middle of nowhere.

There only used to be 1 dead zone for me in Bear Creek Village neighborhood (I visit family there often) until some company(ies) put up a dozen or so new cell towers all over Green Mountain and now I have 4 dead zones that I know about: On Alameda Pkwy. near Green Mountain high school, 2 on the loop around Bear Creek Village and one going East on Morrison road as it goes down the hill towards Fox Hollow golf course. I used to have AT&T years ago and they had signal all over Green Mountain (except 1 dead zone on Union). Wonder if they are any good yet? I am looking to change soon.

At&t sucks a fat one! phone usually never works. Rockies games mean no service at all. People call me and it never rings through. My girlfriend has AT&T also and we can't call each other in our house. AT&T is lame!

Only on Edge does it seem to be reliable in my apartment. I'm getting more dropped calls these days than before. Not sure if it's the upgrade to 3.0 software or what, but it's getting really annoying. I love my phone, but I need to be able to actually talk on it!

Used to be great but all of a sudden calls are dropped from inside the building or no reception at all. Just started in July / August '09. Guess I have to change carriers.

Ugraded to the new iPhone 3gs from the first gen iPhone and my reception is worse than ever. I use to have decent bars and can use the phone with little or no problem. Now I have to hope that I can finish a conversation

Poor reception at home - I have to go upstairs, or near a window {sometimes works}, or outside. I'm on AT&T, but my friends with Sprint or Verizon also get poor reception in my house. Looking to the Towers map, it's not surprising many around the Wash Park area complain of poor cell reception. All the towers appear to be east of University or west of Santa Fe. and north of Ellsworth or south of Hampden. I can't image why no one has any towers along Broadway - the central main N-S street in Denver, or in this heavily populated neighborhood. Please invest in a new, additional tower in this area! It's very annoying, when I can get 5 bars up on mountaintops 40 miles outside of of town...

The service was fine until approx April 2009. I have called Verizon 3 times now, and as of 7 / 25 / 09, they say they lost a lease on a tower and are working to improve the service, but since it is marginal, they are willing to release me from my contract. Calls get dropped, but mostly, the connection is so poor I have to sit still, in the right location, and not move my head.

Reception comes and goes so quick that unless you can have a full conversation in under a minute, it ain't happening. To add insult to injury, Sprint claims that they have perfect service in this area. It isn't the phone either, as anyone with a Sprint phone can't get service. If you're in this area, avoid Sprint at all cost. Otherwise, you'll be carrying around a nice cell phone paperweight.
