RIM is watching its BlackBerry sales slip in every country except the US, the company acknowledged in an SEC filing published Friday. Despite selling a record 11.2 million BlackBerries in its last quarter, its sales revenue outside of the US fell 1.4 percent overall. Its performance in the US was mostly propped up by the launch of the Bold 9650 and Buy One Get One deals like those at Verizon that guaranteed two units sold for the price of one.
