I recently went to Best Buy to see how much they would give me for my iPhone 4 and they said it was worth $267 (something like that), which is cool cause that covers the cost of the phone(16gb) plus ATT's $18 upgrade fee. Basically they are giving me something like $49 for trading my phone in. My question is, since the iPhone 4S is being released tomorrow, do you think Best Buy's trade in value will change tomorrow? Cause if so i can live without my phone for a night and i'll go trade it in now. My girlfriend has a 3GS and her trade in value was $80. Both of us are getting iPhone's delivered tomorrow.
