Cingular will soon announce the availability of the Ipaq hw6515, another smartphone in a long list of supposed BlackBerry Killers, and rumor has it that this dog won’t hunt. It was initially thought that by the time the hw6515 was released in the U.S., there would be an update to Windows Mobile 5, howerver, Pocket PC Thoughts reports that because of ROM limitations, the hw6515 will never support the OS that was supposed to make it a BlackBerry Killer in the first place.
