The HTC TyTN (also known as the HTC Hermes and the HTC P4500) is an Internet-enabled Windows Mobile Pocket PC smartphone 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 including 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 phones 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 Also on AT&T, the TyTN was superseded by the HTC TyTN II, known as the AT&T 8925 and the AT&T Tilt.
Besides the branding differences, there are several models of the HTC TyTN: the TyTN 100, the TyTN 200, and the TyTN 300. The TyTN 100 has no front-facing camera or a 1-megapixel front-facing camera; the TyTN 200 has a 1-megapixel front-facing camera; and the TyTN 300 has a 3-megapixel front-facing camera.
The TyTN Model was sold as:
- HTC TyTN 100
- HTC TyTN 200
- HTC TyTN 300
- T-Mobile MDA Vario II
The TyTN shipped with Windows Mobile 5 AKU 2.3. HTC released AKU3 ROMs to carriers, though it was up to the carriers to provide updates to end users. In July 2007, HTC released a generic update to Windows Mobile 6, freely available to the public. In November 2007, AT&T released an update to Windows Mobile 6.
Official ROM updates are or were available for several versions of the TyTN, including the AT&T/Cingular 8525, the Dopod 838Pro, the i-mate JASJAM, the O2 XDA Trion, and the Orange SPV M3100 (AKU 3.3.0).
