You dont need to change anything over... Just call them and the books will be sent to the device...

Wait a day and cancel it... When you cancel it, make sure they add the Blackberry Enabler Feature back on...

You cant get the books without a data plan.... Perhaps this is the reason these apps are working for some (had a data plan at one time and have the books) and not working for others (never had a data plan ie.. the books)
