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.

Have always had pretty good reception

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.

lucky if you get 2 bars

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.
