I live on the ground floor and my building effectively blocks reception inside my apartment (even though service outside on 9th Ave is perfect and the AT&T cell tower is nearby on 811 10th Ave). I have become aware of the concerns and limitations regarding home installed cell repeaters and the expense of large industrial repeaters (and the requirement for carrier approval). Especially in Manhattan, it is not easy for the consumer to take measures to improve cellular reception. At the Web 2.0 Conference in November 2008, Ralph de la Vega CEO of AT&T Mobility, indicated that AT&T will initiate market testing of Femtocell technology in 2009. He also indicated plans to use an enhanced 850 MHz spectrum to improve signal in densely populated areas. These are both important enhancements. In the meantime, I really enjoy my iPhone but the reception is unreliable and I really want to use the iPhone. Verizon is much more immune to signal deterioration in the city.

almost no reception inside my 6 story building since ATT lost its lease on top of the Mark Hotel on 77th St.due to renovation there. They need to replace this tower. We receive calls but they get immediately cut off. We are now 10075 but I am reporting this as 10021 because Mobiledia does not know the new zip code has been created and will not accept a report for 10075

Even though our building is 3 blocks from Columbus Circle, I get terrible reception on my iPhone, to the point where I need to stand by the window in our apt to take calls. Overall, I have had a pretty dismal experience, anywhere in NYC, with the AT&T service required of all iPhones. I love the iPhone as a device, but really miss my Verizon service. Guess you can't have your cake and eat it too...

Very good voice quality. Data isn't as great as it should be.

Voice is okay, Data is painfully slow. Must be near a window.

lousy, fluctuating reception, but often none at all on and around campus

Generally I have no problems with reception at all anywhere in the neighborhood or in my apartment with the exception of one room. Also work in WTC area and reception is excellent everywhere in the area.

Dropped calls and hours of my phone "searching" for service but never finding it.

perfect reception with a phone service originating from las vegas.

Outdoors on the sidewalk there are 1-2 bars, sometimes up to 3. But in our 4th floor apartment there is barely enough signal to send a text message when you are hanging out the window. It has been a hellish year living with a phone you have to go outside to use. When I hear my phone ring and see who it is, I am filled with rage that I can't answer the call. Verizon said there was nothing they could do, so we're both switching to AT&T. I hear Verizon is better in general but I need my phone to work where I LIVE.
