Ok so it's a simple process, if your on ATT
Go to this link:
https://attbb.tradein-program.com/manufacturer
Follow the steps on that page to select your iPhone. Iphone 4/4s will give you $200 5/5s will give you $300. Take a screen shot of the final quote page with the promo code. Go to your local ATT store and they will offer you whatever price for it and you give them the promo code from your screen shot which bumps the price to whatever is applicable.
They will give you a gift card you can apply to your bill. Easy peasy.
The other $200 is a promo from Samsung that is mailed to you in the form of a check or redeemed instantly at Best Buy. ANY working smartphone is worth $200 when you preorder the Galaxy note. The day you pick up the note, bring your smartphone and they take $200 off the price of purchase.
So in total for me that's $400 in savings and what $330 for the note with tax? It's a no brainer.
