I started a small company that fixes Iphones.
The iPhone was first released in 2007, how long have you been fixing them?
I have done it for a while for just my friends and relatives, but with the booming market, it is a no brainer. People aren't smart enough to fix these things it seems.
They are quite complex machines, very versatile.  Users can do just about anything with their iPhone nowadays.  Text messaging, navigation, etc.  The phone has been transformed since the iPhone.
It has, but I think people and their laziness to learn how to fix has created a market for others.
I believe that most people are afraid to fix their own phones based on the complexity behind the multi-touch screens and virtual keyboard.  This is similar to many other products.
