It seems as if BlackBerry users are not happy with their smartphones.

According to a survey conducted by Crowd Science of smartphone owners, around 40% of BlackBerry users have decided to change their device to Apple's iPhone. And nearly 32% BlackBerry users would change their BlackBerry device to Google's Android Nexus one.

The study also revealed that around 90% of Apple's iPhone and Google's Android users have not planned to switch to any other device when their contract expires. BlackBerry's score was around only 66%.

The study also show that many BlackBerry users have decided to stay as BlackBerry users only, but the rate is much lower as compared to other smartphone producers. This would imply that Apple and Google have a chance to lure Research In Motion's users.
