Steve Jobs
Apple began work on the first iPhone in 2005 and the first iPhone was released on June 29, 2007. The iPhone created such a sensation that a survey indicated six out of ten Americans were aware of its release. "Time" declared it "Invention of the Year" for 2007. The completed iPhone had multimedia capabilities and functioned as a quad-band touch screen smartphone. A year later, the iPhone 3G was released in July 2008 with three key features: support for GPS, 3G data and tri-band UMTS/HSDPA. In June 2009, the iPhone 3GS, whose improvements included voice control, a better camera, and a faster processor, was introduced by Phil Schiller. The iPhone 4 is thinner than previous models, has a five megapixel camera capable of recording video in 720p HD, and adds a secondary front-facing camera for video calls. A major feature of the iPhone 4S, introduced in October 2011, was Siri, a virtual assistant capable of voice recognition.
History of iPhone
Also on August 24, 2007, Engadget reported, by way of photos and a video clip, that they were called by the "iPhoneSimFree" team, who offered to show Engadget a demonstration of unlocking iPhone using a software-only method. Unlike Hotz's hardware hack, the code in this hack was not made available to the general public. Sales of the unlock started on September 10. These sales occurred through several resellers who were able to order "keys" from iPhoneSimFree, then pass the "keys" to customers, allowing the customers to use the software. On September 11, after one day of sales, the iPhone Dev Team announced that they had created a working "software unlock", and released it to the public for free. Utilizing requires some technical knowledge, although a simpler, GUI-based version was under construction. AnySim and iUnlock Reloaded, two free, GUI-based unlocking programs, have since been made available.
