Japanese site, Ameblo, has found an XML file on the HTC Tawain MMS site that references a new Windows Phone 7.5 Mango device called the HTC Radar C110e. The XML file (found here) seems to be used in specifing formatting attributes for MMS picture messages sent to the device. We don’t have many details on the HTC Radar other than its 480 x 800 pixel screen resolution and Internet Explorer 9.0 browser, but there has been some speculation by Ameblo that it may be another name for the HTC Omega.
Ameblo has also found references to another Windows Phone 7 from HTC called the TITAN X310e. Again there aren’t many details as to what kind of special specifications this device might have, nor what it might look like. However, given the name “Titan” I might guess that it could have a sliding keyboard similar to the old “TyTN” and “TyTN 2” devices that we saw from HTC many years ago.
