Smartphone
The iPhone was "not a smartphone by conventional terms, being that a smartphone is a platform device that allows software to be installed," until the opening of Apple's App Store a year later, which became a common means for smartphone software distribution and installation. The first iPhone also faced criticism for not supporting the latest 3G wireless network standards, but was praised for its hardware and software design, and its June 2007 release was met with heavy demand, with customers waiting in lines outside Apple Store locations to be among the first to purchase it.
