According to the leaked specifications for the HTC HD3, features were one thing not mentioned in depth, although there are a few basics known, which is why this section receives a 3 star rating; a proper rating cannot be given on something that no one knows about just yet. This means there is mostly speculation as to what the HD3 will have going for it.
The HD3 will include video playback at 1080p and HD video recording at 720p, both of which are the “going rate" for video these days. In addition, leaked specs claim the HD3 will have room for an HDMI output as well. There is no word yet on audio at all, except that there is a 3.5 mmm headphone jack available, or on what video formats HD3 will support. However going by the HD2’s capabilities, the likely scenario will be that HD3 can handle no less than the following video formats:
wmv, .asf, .mp4, .3gp, .3g2, .m4v and .avi
And no less than the following for audio formats:
aac, .amr, .m4a, .mid, .mp3, .mp4, .qcp, .wav, .wma
Again, things can only get better, right? As for the camera, while the HD2 sports a 5-megapixel, the HTC HD3 will reportedly sport an 8-megapixel camera with dual LED flash. Again, if the HD2 Is any indication for what the HD3 will bring us, the camera will also have a widescreen capture capability and digital zoom. However, auto focus and in built photo editing would have been nice, but there is still hope yet, as these are early preview (leaked) specs.
As for its wireless capabilities, it will of course use Bluetooth and have Wi-Fi (802.11 b/g) capabilities as well as 3G capabilities. If the HD3 is like its predecessor, it will support GPS and AGPS as well as the GSM band at the 850/900/1800/1900 MHz frequencies and WCDMA/HSPA at the 1700 MHz (AWS) / 2100 MHz frequencies. It is also believed by some that the HD3 will sport 4G capabilities as well. I think HTC just might include 4G as an option, especially considering the Evo release; but then again, this is just speculation on my part.
As for the email and messaging, it is only speculation but HD3 should at least have the same basic features as HD2 including One Exchange and POP/IMAP capabilities. However, with the addition of Windows series 7 phone OS with Sense UI atop the HD3, I believe all its features, such as email, messaging, chat and others will be upgraded to make their use easier, especially since HTC’s Sense UI is designed for such a purpose.
