The BlackBerry 9800 will go head-to-head with the iPhone next month in what could be a first for the rivalry, a leak from within RIM claims. AT&T should not only carry the touchscreen slider in mid-to-late June but is placing an unusually large order for a number "easily exceeding" 1 million units. It's not known by BGR how these numbers would be distributed, but this would presumably be spread over weeks and possibly months.
