Well, the title should have read “Three More…” but we’ve already spoken about HTC’s button-less phone so that makes it two. All we’ve found about these phones are a couple of pictures and some specs.
The first phone is spoken of as HTC Nexus Mini, but that is not confirmed and in fact the sources have even found out that this phone’s model number is A3380. The design bears resemblance to the Nexus One, including the trackball in the middle. It looks like the phone has a front-facing camera but it might be a light or proximity sensor. The buttons give a clear indication that the Nexus Mini or A3380 is Android-based.
The other phone in question could be Desire HD’s successor. The design is very similar to it, but the phone has a rounded form-factor which was not seen in the Desire HD or the Nexus One. The front-facing camera is quite prominent but the screen itself looks a little smaller than that of the Desire HD.
So will you see these phones from HTC’s repertoire at the MWC next month? It's just a matter of time now, really.
