The Apple iPhone is finally coming to Verizon Wireless, and among the big questions are whether the move leads to a significant exodus of customers from AT&T to Verizon Wireless, or not. We have five iPhones in use in the immediate family so I will be anxious to see what happens. It already appears that half the accounts are in no danger of any provider shifts. But three of the devices are used mostly in New York and Los Angeles, and there are significant reliability issues for at least one or two of those accounts, fairly regularly.
If I had to guess, I'd say two of the lines could shift. If that is replicated across the whole iPhone user base, it would be a big deal. I think I'd be surprised if three of five shifted to Verizon. That would be a really big deal.
