So you are looking for a new cell phone and with so many a choices on the market, one thing is clear. The Apple iPhone in its many varieties was a game-changer. The launch of the iPhone in 2007 brought usable touch screen technology to the cell phone. Every year since the launch of the iPhone Apple has released a new version of their iPhone, giving users an upgrade path if they wanted. They have added new features every year that other cell phones have had for years like multi-tasking and MMS. But when it comes down to it the iPhone has redefined what a cell phone is like and it, along with the Android competition has forever changed the way we look at phones. It has now been a month since the retail release of the newest iteration of the iPhone, the iPhone 4 and after all of the hoopla of the launch event and subsequent Antennagate surrounding the iPhone 4, I've decided to take a close look at the phone, its hardware and its software to answer the question: Is the iPhone 4 a worthy update to the iPhone 3GS? Let's start with a brief history of the iPhone and its successors.
