See iOS versions. iPhone 3G - June 2008 The higher-speed 3G data service was very welcome. The 3G added many improvements, including GPS. However, most significantly, the 3G was introduced with an application platform that made the iPhone a general-purpose computer and turned the mobile world upside down. The 3G also debuted in Canada and other parts of the world (see SIM lock). See iOS versions. First iPhone - June 2007 Introduced in the U.S. exclusively from AT&T, the first GSM-based iPhone was greeted with extraordinary enthusiasm (see "Quite a Frenzy" in iPhone). Although users raved, the first model used the GPRS and EDGE data networks, which were painfully slow for surfing the Web. See iOS versions.
