Cheap Iphones in the streets
Sometimes you can get this kind of offers. Someone will try to sell you a really nice iPhone for 200 or 250 USD. These phones are inside the box, brand new. The problem is that there is a lot of problems that can happen in this transaction.
1 - you can get a clone. (not a real iPhone but look like a real one).
2 - the person can change the boxes without your notice and when you open the box you get a rock.
So never go for good deals like this.
