It's all about Nokia 5800.
The Nokia 5800, code-named "Tube," is a Symbian S60 smartphone. It is an XpressMusic series phone, which emphasizes music and multimedia playback. While it has tactile feedback, it doesn't use Nokia's upcoming Haptikos technology.
It has a compatibility mode for Java applications that are not touchscreen-aware. It works by using part of the screen for displaying the essential buttons required by the program.
A prototype of this handset was seen in the 2008 Batman movie, The Dark Knight, Christina Aguilera's "Keeps Gettin' Better" as well as the #1 hit "Womanizer" by Britney Spears. The handset was also seen in Flo Rida's "Right Round", The Pussycat Dolls' "Jai Ho!" and Katy Perry's "Waking Up In Vegas" music videos. The phone has received generally positive reviews, with UK phone magazine Mobile Choice awarding it a full 5 stars in its Feb 8th issue.On January 23rd 2009, Nokia announced it had shipped the millionth 5800 XpressMusic device, even though it still had not been fully released worldwide. In Nokia's Q1 report released on April 16th, 2009 it was announced they had shipped 2.6 million units during the quarter, with cumulative shipments of more than 3 million units since the smartphone's launch in late November 2008.
The Nokia 5800 XpressMusic is not the first touchscreen device in Nokia's range. In 2004, the Nokia 7700 was announced, a Symbian Series 90 device that was cancelled before it reached the market. This was followed by the Nokia 7710 which was an upgraded version of the 7700, which became available during 2005. Nokia also produced the UIQ-based Nokia 6708 phone in 2005, but this was not an in-house development and was bought in from Taiwanese manufacturer BenQ.. Nokia have also produced a range of Maemo-based Internet Tablets which have a touchscreen interface, however these are not mobile phones. The 5800 is, however, Nokia's first Symbian S60 touchscreen device.
The 2007 launch of the rival Apple iPhone demonstrated that at the time, Nokia did not only not have any current touchscreen mobile phones, but since the cancellation of the Symbian Series 90 operating system, it also lacked any sort of suitable platform for developing such a device. Although Nokia asserted with some justification that the Nokia N95 was a comparable or better device, most other manufacturers responded with their own touchscreen devices.
