So, I have the Samsung Galaxy S2X, and I want to get the Iphone 4s. If I trade in my current phone, will I get anything put toward the Iphone 4s? It's in good condition and I've only had it for a year. Also, for example if I have a tab of 66, does that mean I can put 66$ to my tab of the iphone? The tab thing really confuses me haha!
