The HTC Touch Pro (also known as the HTC Raphael, AT&T Fuze, XDA Serra, or MDA Vario IV) is a smartphone from the Touch series of Windows Mobile Pocket PCs designed and marketed by HTC Corporation of Taiwan. Released in 2008, it is an enhanced version of the HTC Touch Diamond with the addition of a left-side slide-out QWERTY keyboard, a microSD card slot, and a camera flash.
The Touch Pro smartphone's functions include those of a camera phone and a portable media player in addition to text messaging and multimedia messaging. It also offers Internet services including e-mail, instant messaging, web browsing, and local Wi-Fi connectivity. Depending on its market, it is a quad-band GSM or quad-band UMTS phone with GPRS, EDGE, UMTS, HSDPA, and HSUPA or a tri-band CDMA phone with 1xEV-DO Rev A. All versions feature TouchFLO 3D — a new enhanced version of the TouchFLO interface, unique only to the latest Touch series. In March 2009, HTC announced a new version, the Touch Pro2 which has a larger screen (3.6") and a redesigned slide out (and tilted) QWERTY keyboard with spaces between the keys.
The XDAndroid project makes it possible to run Android on HTC Windows Mobile phones, including the Touch Pro.
As stated, the HTC Touch Pro[3] has three versions: the Raphael 100, which is GSM or UMTS, the Raphael 800, which is CDMA, and a Verizon-specific CDMA variant with less RAM and a unique keyboard layout, the Raphael 500. Listed below are various companies that have confirmed or are speculated to carry the Pro along with their carrier version names (if any).
The following specs are for the retail version of the Pro. Carriers may sell versions of the Pro with specifications that vary from this.
There's a good reason that we keep mentioning the HTC Touch Pro, as both phones are more or less identical hardware-wise. The Xperia is being manufactured by HTC, though Sony Ericsson have gone to lengths to communicate that they have developed the phone without HTC:s input.
