This rom does have the Sprint startup animation & Sprint PCS data connection bubble. However both can be remedy easily and do not impair your carrier-specific operations/functions from operating correctly if not changed...
To change the Sprint PCS data bubble follow these steps:
Go to Start-->Settings-->Connections-->Connections...
1. Click on "Manage Existing Connections".
2. Click on "Edit" to change the name of the Srint PCS #777 to your carrier.
3. Under "Enter a name for the connection", enter your carrier's name.
4. Click "Next"
5. Enter the number your carrier utilizes for data connection.
6. Click "Next"
7. Enter the values for "Username", Password", and Domain. For me, Username was (phone #
@Alltel.com. Password was left blank and so was domain.
8. Click "Finish". Another dialog box should prompt you to save this connection. Again, save it as your carrier's name.
Now...
To disable/modify the Sprint startup animation/sound:
You will need a registry editor of personal choice (I use Total Commander). I will not go into detail regarding making animations nor sound formats. I will provide the location for your own maodification...
Go to-->HKLM-->Software-->HTC-->StartupAnimation.
Make changes here as you see fit.
