Upgrade mobile phones are the agreements between the users and service providers in order to extend the contract. Users are even not required to change their old phone numbers for this extension.
I"ve never been a huge fan of Apple. As an engineer it bothered me that their products were always long on form and short on function. Secretly, I never thought I was cool enough to own one! I am a PC. My wife got an iPhone. Like many, it was her first foray into the smartphone world and she loved it. In fact she"d never gotten excited about a piece of technology and she was incredibly excited about the iPhone. I was jealous and ended up getting one for myself. It was, in a word, a revelation. Moving from a clunky, hard to use, no app device like a Windows Mobile® phone to an iPhoneđ„× is like becoming an Eloi after living life as a Morlock. Everything just worked, and it was cool.
