How much would I have to buy a used iphone4s for to make a good resale profit?

This persons willing to sell her iphone 4s for $140 but the lock buttons broken. I could get it fixed for about 40-50 dollars but i'm looking to resale. How much would I have to get it for to make a good profit

300 bucks is a reasonable resale value for a 16gb iPhone 4s in good shape.

The carrier Virgin-Mobile is currently selling the iPhone 4s for $400 & $300 (16GB / 8GB), brand new. These include a 1 year warranty from Apple. (Link below ~ see link)

Might be difficult to resell a Smartphone with "no warranty" at all. ~ B

  • Who gets the profit in game company? So let's say you have a team of 30 people that make games for iphone and android. Who get's the profit? The founder? Boss? Or is the profit given and divided to each person in the company?
  • Where can I get custom iPhone cases printed for resale? I'm looking to have some illustrations, graphic designs etc etc etc printed onto iPhone cases as cheaply as possible (but not so cheaply that they're rubbish quality) so that I can then resell them on sites like bigcartel and etsy. I was just wondering if anybody knew a site that I could use to get them printed?
