MobileTracker and a number of other websites have reported that Sprint PCS will ship a version of the Treo 600 without a camera. According to these reports, the option will be available as early as April 21.
Everyone I know who has a Treo 600 loves it. But, the presence of a camera in its design can be impediment to selling it in certain markets. I think that offering the Treo 600 without a camera makes a lot of sense.
