Stopped by the Verizon store and it does require you use 2 upgrades unless I added data to one of my kids lines and that's not happening
They said if I come back in a month they will move one of my upgrades up a couple months and make it happen provided the offer is still available which they told me it most likely would be.
If you have 2 upgrades on a family share account this is a sweet deal. I will post back on it in a month.
A couple things. First, the BOGA special on the fascinate is scheduled to run until Sept 30th. Spoke with a verizon rep over the phone for a half hour on Sunday night, asking questions, and moving my brother's account to my account so we could take advantage of the BOGA offer with the Fascinate. The lady didn't know if it would be extended past the 30th.
Secondly, unless they changed their policy in the past year and half, you don't have to maintain the data plan for the fascinate if it is not associated to an active line. 1.5 years ago, I joined a family plan with my mom to take advantage of BOGO for storm. Got two Storms for $200. Both were activated with blackberry data plans. One week after they were activated, my mom couldnt use it, so we had her phone number switched to my old phone which she could use. Verizon then removed the blackberry data plan because the blackberry wasnt active. We were charge for one week of data usage for that phone. My mom remained under contract for voice, but no data. I unlocked the extra storm, sold it for almost $400 on ebay. So basically, I got a storm, made $200, and only had to pay for a week of data on the free storm.
Therefore, unless they've changed their rules, if you have two accounts available for upgrade, you could get two fascinates, maintain a data plan for a few days to a week for the second fascinate, and then inactivate the fascinate and put that number on an old phone. No more data charge until you would activate the other fascinate again.
To get my BOGA fascinates, my mom's (primary line) was able for early upgrade, but my line wasn't (had two more months left). So I merged my brother's line over, upgraded his and my mom's line to fascinates. Once activated, I unactivated my blackberry (stopping blackberry data), added my mom's fascinate to my line, and reactivated my mom's old phone to her line. So I now have the data fee for fascinate, but no longer a blackberry data plan.
Point is, that once you have the BOGA lines activated, you have freedom to move the phones around on your account, and if you wanted to keep one of the phones as a backup, you shouldn't have to pay data on it, if the phone is not currently connected to one of your phone numbers.
