I guess it's a pretty straight forward question. I know current Verizon customers can pre-order, whether upgrade eligible or not. My concern is that there's one line on the family plan that is upgrade eligible on exactly February 10th which is officially the iPhone launch date. I wonder if Verizon would charge the full retail amount through the pre-order in such a case or since the iPhone does not officially launch till the 10th if they would charge the upgrade price? I suppose the same issue arises if you are eligible anytime between the 4th and 10th. I am anticipating that there might be huge back-orders after the first days it goes on sale...so I would prefer to preorder to make sure I don't have to wait weeks.
