With regard to Swype. You have to go back to the Swype website and have them resend you the beta download email. I did it and it worked great. You will need to log into Swype online to send this to your GMail account.
What I found with appbrain is it makes another phone on your list of phones which is OK. Just go to your old phone select all of your apps and add them to your new phone. Once that is done go to the settings tab on the site and select the new DINC as your default.
