What I find frustrating is that after I found out that Best Buy didn't have any ATT phones in stock at all, I called the closest ATT store to find out that they had 5 silver Note 7's that were available first come first served. I went over there and come to find out I couldn't buy one because of the pre-order I already had in place with BB. Even if I cancelled my BB pre-order they said it would take at least a day to register in their system, so basically I'm SOL.
Not true. I canceled my BB preorder and it registered in Sprint's system within 5 minutes. Then again, maybe ATT is different.
And even if it does take a day, you'd might as well cancel at BB. At the very earliest you can still get it tomorrow from an ATT store. BB isn't going to have any for a while (seems like).
