Live pictures of HTC's Artemis and Trinity
The other device, the HTC Trinity, is the successor of the Prophet and is actually a TyTN in candybar design. Both the Trinity and the TyTn have almost the same specifications, while the first has the QWERTY keypad cut off. It sports a white plastic look, which slightly resembles an iPOD, and also there's no GPS although it was expected to have one.
Info on release dates and pricing of the devices is expected soon.
