Don't know what you're all blathering about
I'm on my 3rd iDevice. I got a Gen 1 right about the time the price dropped from $400, then got a 3GS near 2 years later to replace it, and after shattering that got a 4 a few months ago. My wife is still using the 1st Gen (until i get around to replacing the screen on the 3GS to give that to gher, still works flawlessly just broken glass...) Between the two of us, about 800 min/mo average talk time, and combined more than 3GB of data monthly, I have NO ISSUES with AT&T at all.
In several years, I've dropped maybe 10 calls total, legitimately as a fault of AT&T (and who really knows if that was me or the other guy dropping). Not one dropped call on the iPhone 4 since purchase. Yes, there are some dead spots on freeways here where I know I'll drop a call. that is NOT an AT&T issue, that is a local monopoly issue, and effects EVERY carrier. I drop a connection there, but get it back instantly on their towers, then switch back again a few miles later. NO carrier can handle switching in and out of their network, and sprint has no access at all for those 10 miles of freeway. We all deal with this locally, and we all know the spot (there's even billboards warning of the impending call drop area!)
Outside of the few spots, I have FAR superior coverage on AT&T all around the southeast than Verizon. I know of dozens of places Verizon doesn't work at all, more for Sprint, and not a single place AT&T doesn't have at least Edge signal, even out in farm country 50 miles from my home. Most of it is HSDPA+, and gets faster downloads than Sprint 4G. My wife was on Verizon the first 2 years I had an iPhone. She dropped calls weekly, had trouble getting signal at all where she worked, and had to go outside the house to hold a call some days. We're in one of the biggest neighborhoods in the northeast area of our city, and V has 3 towers closer to the house than AT&T does... That's pathetic that I can hold calls inside and she can't. She tried 4 different phones before Verizon stopped offering to exchange them, but would not let her out of her contract as we crossed the 30 day threshold (actually 90 days) trying to confirm it wasn't simply a bad handset.
The monthly bill is within $5 of Verizon for the same plan tier, but i get rollover minutes, hotspots, and there's no data overage charges period (and I have gone over 5GB several times, pushed up to near 20GB on a vacation last fall).
This summer I was in NY, about 25 miles from Manhattan. 1 dropped call in a week, and that was in an office building elevator. AT&T already fixed as much of their service congestion (it was never quality, it was a matter of AIRSPACE) issues as much as the FCC will allow until new spectrum is available. In super dense areas (4 cities, and then only some times of the day), AT&T can have issues, but Verizon does too unsurprisingly.
Data/voice concurrency is the big winner for me. Without that feature, a smart phone is pretty useless to me. Throw in free wifi hotspots, rollover minutes, no caps, no data overages (I'm grandfathered in), its WELL worth $5 more per month. i saved a years worth of the difference on just 1 trip (Verizon would have hit me for some $75 in overages that month, just on data, I've gone over my 900 minute cap 4 times in 12 months and that would have been more than $15 each time on V too). Oh, and verizon as so totally anti-consumer.
Yea, when the iPhone dropped, AT&T got overwhelmed. Their networks crumbled in congested areas. Dropped calls are down 1,000% in Manhattan since then. Where I live, and everywhere within 500 miles I've traveled, AT&T has better coverage than Verizon, and better speed than sprint. What's the fuss? FUD? Oh, any my new job just gave me a Sprint Blackberry. Same device is available on Verizon for less per month, but Verizon is banned by company policy since it's "unreliable in many corporate facilities."
