I am trying to upgrade to the iPhone 6 through Apple's site. I am currently on the Loyalty plan with Verizon ($60/month for 2g data and unlimited voice and texts). When I go through Apple's site, it is requiring me to select a data plan and then it is tacking that on top of my "current voice plan" - increasing my expected monthly bill by $30. When I try to order through Verizon, it allows me to keep my same plan. Here's a screenshot:

I'd like to order through Apple so that I can get the phone faster. My question is, if I do order through Apple, will it mess up my plan? Should I just order it and then call Verizon to make sure the Apple changes to my plan don't carry over? It appears as though when ordering through Apple, the changes in my bill will take effect immediately.
Thanks in advance for your help!
