Its main, unique feature is a user interface named TouchFLO[1] that detects a sweeping motion and can distinguish between a finger and a stylus.

The global launch of the Touch was in Leicester Square, London, on 5 June 2007 (2007-06-05),[2] and the phone was initially available in two colours: black and green.

[7] The CDMA version of the Touch, known as the "HTC Vogue" or the "HTC P3050", has double the RAM and ROM of the original Touch, a faster 400 MHz processor (QualComm MSM7500),[8] and a faster over the air data capability, but no Wi-Fi.

[9][10] This is sold under the name Okta Touch by Telecom in New Zealand.

[17] Wing Linux, an Android version, is in development and available via ROMS, from xda-developers website.
