Ah, the wonders of the great Pyramid. What lies beneath we wonder? Sure, there are theories but nobody really knows for sure. Until CTIA in Orlando next week that is.

No, not the great Pyramid of Giza - we're not interested in that block of old bricks. We're talking the HTC Pyramid, which has once again turned up online.

This time, the reveal comes in the form of a rendering from the same Chinese site that brought us details of two new HTC Windows Phone 7 handsets earlier.

We've heard before that the Pyramid is to T-Mobile (in the US) what the Evo 4G is to Sprint, the Thunderbolt is to Verizon, and the Inspire 4G is to AT&T. That's right we're talking about a 4G HSPA+ connected handset. 

And one packing Android 3.0 apparently - although we seriously doubt it (2.3 or 2.4 is much more likely). It will be, according to numerous reports, packing a dual-core CPU though - the Qualcomm MSM8260 1.2 GHz Snapdragon - as well as a healthy 768MB of RAM. 

The Pyramid's display is said to be qHD (960x540) and apparently it is packing two cameras, front and rear, weighing in at 1.3-megapixel and 8-megapixel respectively.

Previous reports suggested that the phone could be landing in stores as early as May 2011 - and we're now expecting to see it on show at the CTIA expo in Orlando next week.

Pocket-lint will, of course, be on hand at the Wireless Association's big Florida shindig, so be sure to check back for all the juicy details.
