The HTC Inspire is an HSPA+ on AT&T. They call it a 4G phone because it can match speeds that Sprint and Verizon advertise for their true 4G devices. The Inspire is based closely off of the Desire HD, which was released in Europe. It has a 4.3" WVGA display with 768MB of RAM and 1GHz CPU. It runs Android 2.2.1.
