I want to get one with T-Mobile because they have an awesome trade in promotion and very good coverage in my area. I have to get it through the T-mobile store because of the financing and trade in however. I want to purchase the 64 GB Silver 6 Plus model. Would the best course of action be to wait at a T-Mobile store on Friday morning? Or should I just preorder one online right now? My research tells me it could be into late October if I preordered now, and I am more inclined to take things into my own hands and reach out to stores to get one sooner than that (after it launches of course). What are your thoughts?
