Cabir.B is a minor variant of Cabir.A, the only significant difference is that the Cabir.B displays different text on the start dialog when the worm starts to execute for the first time or when the phone reboots. Cabir.A displays text "Caribe-VZ/29a" while Cabir.B displays the text that contains just the word "Caribe".

There is also repacked version of Cabir.B that is packed into SIS file, which installs the worm into different directory and shows text popup at SIS install. But this is not a new variant as worm executables are fully identical to original Cabir.B and all differences are due to settings in the repacked SIS file.
