The Palm Pre ˈpriː, styled as palm prē, is a multitasking smartphone that was designed and marketed by Palm with a multi-touch screen and a sliding keyboard. The smartphone was the first to use Palm's Linux-based mobile operating system, webOS. The Pre functions as a camera phone and a portable media player, and has location and navigation capabilities. The Pre also serves as a personal information manager, has a number of communication and collaboration applications, and has Bluetooth and Wi-Fi connectivity built-in. The Pre was launched in the United States of America on June 6, 2009, with Sprint, and later in Canada with Bell Mobility. A GSM version of the original Pre was launched later in 2009 on a number of networks in Europe and in Mexico. A revised model, the Palm Pre Plus, which doubled the available memory and internal storage, was launched on January 25, 2010, for Verizon Wireless and later released on AT&T Mobility on May 16, 2010. The third generation of Palm Pre, the Palm Pre 2, which uses HP webOS 2.0, was announced October 2010. The Palm Pre became the fastest selling phone in Sprint's history, and it has been a widely praised device. Apple accused the Pre of copying elements of the user interface, with Apple COO Tim Cook stating that "we will not stand for people ripping off our IP" and Palm responding that they "have the tools necessary to defend [themselves]", hinting at Palm's large portfolio of patents. On May 19, 2009, Sprint and Palm announced the Pre would be available beginning June 6, 2009. On May 28, 2009, Verizon Wireless announced that it would also carry the Palm Pre in "about six months." A later comment from a Sprint spokesperson indicated that the launch carrier would have US exclusivity rights to the Pre "through 2009." Sprint's CEO, Dan Hesse, commented that his company and Palm had agreed not to discuss the length of the exclusivity deal, but remarked that "it's not six months.
