I have consistently had problems with dropped calls ever since I switched from the original iPhone to the iPhone 3GS, they replaced my phone twice because of it. It would work for a while, but then drop calls, or get 10 call failures before actually placing a call, just to be dropped minutes later...
Yesterday I finally upgraded to 4.0.2 and it is even worse! Not only do I barely get any signal in my house, even when it shows I have a signal it still doesn't work. The problem seems to be when it goes into sleep mode it disconnects, because when I unlock it, a swarm of text messages and voice mails from missed calls I never received pour in...
I finally called up AT&T to see if there was anything they could do (maybe give me one of the femtocells to keep my 5 iPhone family plan happy (bill is almost $300 a month)... I was greeted by an unfriendly and unhelpful customer service agent. She pretty much told me there was nothing she could do (and when I asked about the femtocell she had no idea what it was, didn't even offer for me to buy it), and then she said its just the network, it happens to her all the time, I am probably in an area with poor coverage.
I told her to look it up on the AT&T coverage map it shows "best coverage" all around my house and where I live, pretty much most of Long Island. To which she said "coverage is not at all guaranteed", I flipped a bird and said "what the fu*k does that even mean, so I can get an at&t phone and pay for the service and you can't even guarantee I get service in any location around the world, even if you advertise it" to which she responded "yup". And I said, that's just ridiculous, I might as well switch to a carrier such as sprint or verizion (my parents have one of each) and they get service in our household. And then she said "Go ahead and switch". I don't remember exactly what I said after that, but she followed with other dumb remarks, such as, it could just be what your house is made of, or do you live underground? I'm sure I live in a cave lady... But I really can't bash all the Customer service agents at AT&T, some are great and very helpful.
Never the less, I was very pissed and disappointed with how AT&T is handling itself. Never have I had such poor customer service. When I had nextel and complained about their crappy service, they were very apologetic and offered me free stuff, and even if I never mentioned dropping them, but even hinted at the possibility, they would offer me upgrades and the works just to keep me... AT&T is just hit or miss, when the network works, its great and super fast, but if your in a high traffic or any other area, its the pits... Which is why I think people on the forums have such a hard time understanding these complaints. I bet the reason for the big change in satisfaction surveys has to do with geographic location. When I was in any other state but NY the service worked when it said I had service, but even then I could have full service, travel 10ft and get No service to show up on the iPhone, very spotty at best.
I am definitely going to switch my entire family plan over to verizion when our contracts are up in a year, I really hope they get the iPhone, if not, droid here I come! But to the rest of the community, has this ever happened to anyone else but me? Should I call back AT&T, at this point I would be willing to buy the femtocell, my phone doesn't work in passive mode, only gets service when I am on it and unlocked.
EDIT:
I actually looked up the femtocell, which is now called microcell to make sure I wasn't going crazy and to see if it is available in my area (which it is), and I saw a video that I just find hilarious! If you go to the following link and click on "increased signal strength" in the interactive video that loads on AT&T website for the microcell, it starts to play a video that actually shows how crappy their service is, with the guy having to hang out of the window to make a call... WTF? AT&T should fire whoever makes their commercials...
