Hello everyone. I just recently upgraded to a 32 gig GS6 Edge Plus. Great phone, but I'm thinking I should have gone with the 64 gig model. I'm still within my 14 day window. Can I swap out the phone at a Verizon Corporate store, or do I have to mail back the device, and go through the process again? The 32 gig model was ordered from the website. I appreciate your feedback.
