The HTC Kaiser has been the presumptive successor to the AT&T 8525 for a few months now, and recent information has done nothing but confirm this assumption. New reports are popping up online which indicate that the Kaiser will come to AT&T in late August or early September 2007 in the form of the AT&T Tilt, presumably AT&T’s designation for the first Windows Mobile device with a flip-up, angled screen.
