Reception just got horrible over the last week or so. Sprint said they fixed the antenna but it doesn't seem to have any change. I used to get 3-4 bars in my house now I get 1 bar with 95% of my calls being dropped!

I can connect one in three or four calls if I stand near the window. Data is even more spotty.

Terrible! The service is awful everywhere in this city. Get AT&T only if you are a) not relying on cell service for business b) nostalgic for the land line days because you will need one c) a masochist. I only wish I didn't sign up for that two year contract.

Intermittently fuctuates between 1 and 2 bars; using the phone as modem is impossible.

In the Richmond District, I basically teeter between no reception and one bar (on Edge). I rarely land on 3G and when I do, it is usually when I am downtown or driving down 19th Ave through the Sunset District. AT&T is disappointingly unreliable; I wish I could switch carriers but I'm tied to this 2-year contract. Avoid going with AT&T if you plan to live in the city.

AT&T = Worst carrier ever! Constant disappointment. If I had a dime for every dropped call I'd be a millionaire. Phone works fine in some other markets... there's nothing wrong with the phone.

the iPHONE 3GS has been a big disappointment. For all the money we pay per month it's not worth it. It drops calls all over the place especially at home in Emeryville. No reception. It switches between Edge and 3G while I'm in the same spot. ATT and APPLE owe us money back!

went from Verizon to AT&T last year---only because I wanted an iPhone. while I love the device, the AT&T coverage---both call reception and 3G coverage---is extremely spotty. during my time with Verizon the call quality was near perfect. with AT&T there are dropped calls, ghost voices (echoes), and unreliable 3G even in the middle of SF or Berkeley. if apple was really savvy they would unlock the phone or at least get it over to verizon. rumor is they will----i'll believe it when I see it.

att / cingular didn't work at all, Sprint barely worked, but other than the occasional voice feedback VERIZON has worked without a problem over the last two years

My reception has improved over the last several months. I get decent 3G reception. However, once I start to use the 3G it usually kicks back over to EDGE. At least I am able to talk on my phone these days, that's an improvement from a year ago.

The phones don't work on the top of Protrero Hill. I called AT&T and they said the cell towers or on the bottom of the hill!

I have Working Assets (now Credo) which uses the Sprint network. I have great reception and have had good results all over the Bay Area.

Had to return my iphone after 1 day as there was no reception at my house. Went back to Sprint and the Palm Pre which has a weak signal here but at least has some coverage.

Barely works on the south side of the house closest to the street. Doesn't work at all on the North side of the house.

i work at the garage and ATT seems 2 be the carrier with the strongest signal as well as the entire airport

I have about 2 square feet in my home in which I can use my phone. If I sit back or sneeze, the call's history. Also, I see people talking on their phones in places where I have no reception, all the time. Also, Sprint to Sprint calls sound like I'm talking through a tin cup.

I get very good coverage at my house. I've used AT&T before and had to sit outside to talk on my phone. My coverage is pretty good in the neighborhood and near home but as I head towards Mission and Valencia in the Mission District my coverage worsens.

Dead, dead, dead. Market St.between Clayton and Diamond Heights is a zero-bar AT&T dead zone. Diamond Heights Shopping Center: Never completed a call with o a drop.

I have 2 bars at best. My phone won't even ring at times and goes automatically into voicemail. Then I won't even get my voicemail messages until the next day if I'm lucky! Same for text messages.

Horrible coverage, and I'm downtown San Francisco. I barely one or two bars and calls are constantly dropped. At times my phone won't even ring and goes directly into voicemail. if someone leaves me a voicemail I don't even get it until a day later...
