"While October's outage, focused on EMEA particularly, has hurt RIM's reputation for reliability, we do not expect it to have a substantial impact and expect a decent Q4 performance there," he added.
Llamas and Shepherd both said that whatever success RIM has outside of North America, it needs to reassert its position in the U.S. and Canada, its home country, with products based on its new BBX platform.
Llamas noted that RIM didn't release a new BlackBerry in North American in 2011 until mid-year, while HTC, Samsung and Motorola were releasing new smartphones "almost every month."
Llamas added: "Repetition is reputation, and if RIM's not repeatedly out there with new products, it will lose mindshare."
