mon for smartphones to have a physical T9 numeric keypad or QWERTY keyboard in either a candybar or sliding form factor. Some smartphones had resistive touchscreens, which allowed for virtual keyboards and handwriting input with a finger or a stylus, thus also allowing easy entry of Asian characters. In 2007, the LG Prada was the first mobile phone released with a large capacitive touchscreen. Later that year, Apple Computer introduced the iPhone. The iPhone was also designed around a large capacitive touchscreen, but added support for multi-touch gestures (for interactions such as "pinching" to zoom in on photos and web pages). Such phones were notable for abandoning the use of a stylus, keyboard, or keypad typical for smartphones at the time, in favor of a capacitive touchscreen for direct finger input as its only input type. The invention of the touchscreen smartphone is often attributed to Apple, but they actually made the smartphone as we know it today something mainstream due to the company's popularity in the US (and to a lesser extent worldwide) and they made popular the way that people interact with smartphones. Following the iPhone's success despite its original retail price of over US$500, other smartphone manufacturers started to use the same basic design of the iPhone. The iPhone was at first "not a smartphone by conventional terms, being (...) a platform device that allows software to be installed",. A year later, it followed platforms like PalmOS, Symbian and Windows Mobile in allowing apps to be installed. It did so through Apple's App Store, an online distribution platform which was present on the phone and controlled and monetized by Apple. This 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. The screen-focused hardware of phones centered around a capacitive touchscreen stimulated the software to focus on features such as a web browser designed to render full web pages (as opposed to stripped down WAP services), multimedia functionality (such as videos), and online services such as maps apps. This was a key factor in the success of the form factor. The advantages of a design around a capacitive touchscreen affected the development of another smartphone OS platform, Android, with a more BlackBerry-like prototype device scrapped in favor of a touchscreen device with a slide-out physical keyboard, as Google's engineers thought at the time that a touchscreen could not completely replace a physical keyboard and buttons. The first And
