Rockville, Maryland — In a just-released survey report, ChangeWave takes a close-up look at the features consumers love and hate most about their iPhones and BlackBerrys.

This report is a follow-up to a previous ChangeWave Smart Phone survey showing a rapidly evolving two-horse race between the Apple (AAPL) iPhone and the Research In Motion (RIMM) BlackBerry – with second tier players like Palm (PALM) and a host of others being pushed to the sidelines.

The previous report showed excellent consumer satisfaction levels for the two smart phone frontrunners – with Apple sporting a 79% Very Satisfied rating for its iPhone models and RIM grabbing a highly respectable 54% rating for the BlackBerry.
