Do you need a phone signal or can they work on gps alone?
My experience is with an AT&T iPhone. All currently available information is that the Verizon iPhone will operate the same. It is certainly in the realm of possibility that there will be some differences.
On the AT&T iPhone without a cell signal the phone hits the battery pretty hard looking for a signal. Putting the phone in airplane mode is the obvious response. Unfortunately the phone GPS won't acquire a signal in airplane mode. There is no error message - it just sits there and hunts.
I've been very happy with Charts & Tides, including the excellent ActiveCaptain information. Offshore away from cell signals I keep the phone in airplane mode except for when I'm explicitly looking at Charts & Tides or one of my other GPS/navigation applications. That seems to be a reasonable approach.
I'm hoping that some future upgrade to iOS will give us a way to turn the GPS back on in airplane mode, just as we can currently choose to turn wifi back on in airplane mode.
My partner ordered a Verizon iPhone yesterday - we're looking forward to side-by-side comparisons.
