A German HTC fan blog by the name HTC Inside published a shot from Vodafone's internal inventory system last night, revealing the existence of an HTC phone by the name "Desire 2". Phandroid pointed out that this may be a European version of the upcoming and equally mysterious dual-core Pyramid, and I'd say that's not too farfetched a theory.

We'll probably find out what this thing is at the Mobile World Congress in Barcelona (which starts on the 14th), so the mystery shouldn't last a whole lot longer.
