I'll switch IMMEDIATELY if Verizon can reset my AT&T iPhone. If not, I'll wait until it needs to be replaced. I just got it late last year (G4 iPhone with AT&T). AT&T has a little better service this time than when I had it for my Blackberry in the early 2000s. They were terrible then for customer service, and nearly as bad on coverage area. Now at least you can walk into the AT&T store and get help, whereas you couldn't before. And there is an improved coverage area. But my Verizon phone works perfectly every inch of the way from Los Angeles to Dallas, and has great signal at our house in Ventura County, CA, where AT&T has no service. I've even gotten a good signal on VZW from the middle of the Nevada desert, 250 miles north of Las Vegas and 100 miles from nothing. AT&T; forget it. However, to be fair, there are a few places in Los Angeles where you can't get a VZW signal, but you can get AT&T. But just to be clear, it's 10:1 in favor of VZW.
