Transferring Contacts From One Phone To Another
When transferring from one phone to a new handset if you email accounts set up you will need to log in to the Blackberry service and move the email accounts to the new phone.

Email Portal - O2
By default the O2/RIM portal will use the email address as the username for the email account. This is fine unless your system needs a username that does not match the email address. When setting up a new email address put in an incorrect email address so that set will fail. This failure will result in you being offered advanced set up options, amongst which is the option to specify a username.
