I am meeting up with a person at the verizon store to assure the phone works and is not stolen and so they can see the same with mine. Also so we can be sure our phones are clear of any important or private information.

They are trading me their white iphone 4 (the older one, not the S) with 8GB. It is almost brand new; they bought it about a week ago and hated it. I am trading them my white samsung fascinate, which is about a year old but in almost perfect condition, and $100.

Is this a fair trade for me since it's the older version of the iphone 4 and 8gb? Am I getting a decent deal? I've never done this before so any other advice would be amazing!

Thanks ahead of time
