# HTC TyTN

The HTC TyTN (also known as the HTC Hermes and the HTC P4500) is an Internet-enabled Windows Mobile Pocket PC PDA designed and marketed by High Tech Computer Corporation of Taiwan. It has a touchscreen with a left-side slide-out QWERTY keyboard. The TyTN'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 such as e-mail (including Microsoft's DirectPush push e-mail solution, as well as BlackBerry services with applications provided by BlackBerry-partnered carriers), instant messaging, web browsing, and local Wi-Fi connectivity. It is a quad-band GSM phone with GPRS, and EDGE, and a single/dual band UMTS phone with HSDPA. It is a part of the first line of PDAs directly marketed and sold by HTC. On AT&T/Cingular, the TyTN was the successor to the HTC Wizard, known as the Cingular 8125. Also on AT&T, the TyTN was superseded by the HTC TyTN II, known as the AT&T 8925 and the AT&T Tilt.
