Apple's iPhone is boosting sales of competitive products such as the BlackBerry rather than eating up their market share, according to Research in Motion (RIM) and Nokia.

RIM COO Dennis Kavelman said sales of the BlackBerry increased following the launch of Apple's smartphone, with the touchscreen handset helping to raise awareness of the market and converting voice-only phone users to converged devices

"iPhones get people thinking [about smartphones]... I want to buy them [Apple] a drink."

Nokia's industry liaison VP, Mark Selby, agrees with RIM's sentiments, saying devices such as the iPhone help "stimulate" the market and add credibility when more people begin to talk about convergence.

Asked whether Nokia's forthcoming N96 will be an iPhone killer, Selby replied: "I don't know what there is to kill."

Despite the fanfare about Apple's entry into the market, he said it takes Nokia seven days to sell what Apple has sold in year.
