The HP Pre 3 (styled as Pre3 and pronounced as the English prefix pre, /ˈpriː/) is a touchscreen slider smartphone manufactured by Hewlett-Packard. The device uses webOS, is powered by a Snapdragon processor, and has a 3.6-inch screen. It is conceptually the successor to the Palm Prē 2 and earlier Prē and Prē Plus models.
The HP Pre 3 was announced on February 9, 2011, at the HP webOS "Think Beyond" event held at the Fort Mason Center in San Francisco alongside the Veer and TouchPad. It was commercially released in the United Kingdom on August 17, 2011.
The device supports a new Touch-to-Share proximity-based sharing feature, which allows compatible devices (such as the TouchPad) to instantly exchange data, media, and information via Bluetooth. The Pre 3 has 802.11 b/g/n Wi-Fi, 512 MB of RAM, 8 GB internal storage, Bluetooth v2.1, and a 1230 mAh battery. A 16 GB model was manufactured for AT&T and Verizon  in the United States, both models were never released to the general public.
The Pre 3 was released on August 17, 2011, in the United Kingdom. The next day, August 18, HP announced that it would be discontinuing all webOS devices, including the Pre 3. The phone was never officially released in the United States, although models eventually were sold through the HP employee store in California, and many of those phones ended up on eBay auctions.
Screen and Input 
The HP Pre 3 features a 3.58-inch multi-touch, capacitive touchscreen with a resolution of 800-by-480 pixels. The Pre 3 has three physical buttons for input, including the volume up/down buttons in the side, and the power button in the top. For navigating through the OS, the Pre 3 has a "gesture area", where you can swipe up to enter the card like multitasking view, swipe from right to left to go back in an application, swipe from left to right to go forward, or optionally swipe completely to the right or left to switch applications. Modifier keys combined with gestures enable text selection and cursor positioning, while command shortcuts are triggered by holding a tap in the gesture area while pressing a key on the keyboard.
The Pre 3 supports Bluetooth 2.1, 802.11a/b/g/n Wifi, and HSPA+, as well as GSM, EvDO, and CDMA (depending on the service provider). Along with the HP TouchPad, the Pre 3 supports a new technology called Touch to Share. Touch to Share lets you share URLs, phone calls, text messages, and data for 3rd party apps between the TouchPad and the HP Pre 3 by tapping the phone on the TouchPad's sensor. For example, a web site being browsed on the TouchPad can be transferred to the Pre's browser by tapping the two devices together.

In addition, an update to webOS 2.2.4 was released for update by webOS Doctor  and as an OTA update.
