Long post warning!
First - I can definitely tell you that I have had nothing less than stellar service in Charlotte (where I live), Greensboro, Raleigh, and Myrtle Beach - all of which I visit frequently. I've also had no trouble what so ever at WDW... even in large crowds... even in July/August.
When I had Verizon I never had service ANYWHERE. I also had horrible customer service experiences. Multiple horrible ones. I'll save those unless you really want to know
As for the amazingness that is AT&T, let me tell you this story - which is the reason I will never go to another phone company.
In February I was eating brunch with my Mom, and I had been wearing pants with cargo pockets. Stupid me didn't check my pocket to make sure that I had my iPhone before we walked out, and I ended up losing what felt like a limb. I was completely stricken! I was hoping that it had just been lost around my house somewhere, but just in case I texted "cash reward if this phone is found! Please call ##########" (DH's number), and received a phone call which was a hang up. I called the number over and over until they finally turned my phone off.
I didn't have MobileMe set up, which I definitely will always have now, but MobileMe
can wipe a phone of it's data, and can also track a phone if it's been lost or stolen. Since I didn't have this at the time, AT&T couldn't help me. They sympathized with me, though, and since it's not like they could just give me a new phone, they credited my account until I could get a new one (which was great - most companies won't offer that for people under contract... I would know. Verizon sold me a phone with a known glitch and refused to take responsibility when it messed up... and I still paid for the last 18 months on that contract).
---> Also, on the note of privacy, if an incorrect password is input 10 times the phone automatically wipes itself. Wish I had this set up when I lost it! Not that I had anything
private, per se, but the fact that people were looking at pictures of myself, DH, and my cats just made me feel violated.
My friend had an old 2G and sent it to me as a place holder until I could afford a new phone. AT&T credited my account so that I didn't have to pay for a new sim card and upgraded me to free shipping.
Finally I had saved enough to get a new iPhone 3GS - which is even better than the 3G by far - and AT&T was once again very easy to work with. iTunes also restored my phone completely so that none of my pictures, phone numbers, or settings, or ANYTHING from the old phone. I loved that so much more than I can even say. Once my 3GS was here, it was like my phone had just upgraded itself and nothing had changed! AT&T gave me so many account credits, too - it really helped me save for the new phone.
AT&T's 3G is also faster than Verizon's. I can't stand how slow playing with my mom's droid is. It's also SUPER heavy... the iphone is surprisingly light!
