Verizon has the Iphone finally!

Ok so now Verizon has the Iphone. I was stuck with ATT's crappy service for two years and right when I switch to Sprint, they decide to bring the Iphone to Verizon. Could care less now. I feel like this should have been done when Iphone 4 came out. Now Verizon customers will get screwed because the next Iphone model will go to ATT first. Android will anticipate a hit in sales now that Verizon has Iphones, but not so much with ATT. My question is, now that Verizon has the Iphone, will current ATT customers switch over to Verizon? I gave up on them because of their crappy network, I'm guessing others will as well. Will wait and see.
