According to RBC Dominion Securities Inc. proprietary survey there is an “unprecedented” demand for the iPhone 5 and strong back-to-school buying intentions for the iPad.

A report published in The Globe And Mail says that the survey, taken Aug. 2 to 10, found that 31 per cent of 2,200 respondents were very or somewhat likely to buy the iPhone 5. That significantly exceeds the 25 per cent of respondents who had said they intended to buy the iPhone 4 ahead of its launch more than a year ago. Meanwhile, 66 per cent of existing iPhone users said they were very or somewhat likely to buy the iPhone 5, suggesting many current customers are planning to upgrade.

The potential market for the iPhone is expected to expand significantly when the fifth version of the device comes to Sprint at the end of this year. Some 54 per cent of surveyed Sprint subscribers said they may buy the iPhone.

“With surveys showing the still huge iPhone opportunity, we remain constructive on shares, and view valuation as compelling,” RBC analyst Mike Abramsky said in a research note.
