Ok, this may be an obvious answer, but I just want to be sure before I go ahead with it. Long story short: I'm with Verizon, and I'm on AT&T's web-site to order a new 8gb iPhone 3G. I am going to port my number, but my question is this. When does my service cut off with Verizon? Obviously, if I order the iPhone tonight, it probably won't be here until Friday. I still want to use my VZW Blackberry until the iPhone arrives. So does my VZW service stop once the iPhone is in my hands and I activate it? I know, dumb question. I just figured I would ask since I don't want to be without cell service for a few days. Thanks!
