We first told you about the iPAQ K3 Obsidian in May.  At the time, Engadget had gotten its hands on some officially-unofficial information regarding AT&T’s 2009 line-up, of which the iPAQ K3 was a part.

Now a Vietnamese tech site, VNExpress.net, has some new information on the iPAQ K3, along with photos showing the smartphone with an AT&T logo.  According to the site, the K3 is intended as a replacement for the iPAQ 910 Business Manager, which is sold in the U.S. as an unlocked smartphone. 

Assuming the new information is true, the upcoming iPAQ will also sport an AMOLED screen and a slightly curved QWERTY thumb keyboard.
