The HTC Kaiser is not quite here yet and the release date has been all over the map. While we wait, MoDaCo has pulled together a quick summary of information about potential carriers as well what we know about the software so far.
Among the carriers that will offer it, T-Mobile, Vodafone and AT&T are definitely in the running. Orange is still a maybe. There will also be an unlocked version offered by HTC, namely the P4550. Both the HTC and T-Mobile variants could hit the street in September.
In terms of software, many of the UI enhancements first seen on the HTC P3450 Touch, including some TouchFlo elements, will make their way onto the Kaiser. Both the Opera browser and Worldcard Mobile, a business card reading application, will come pre-installed (MoDaCo has a video of this application in action).
