There are at this time no ROM matching the Orang CID. But you may be able to flash your device with any rom available on the wiki page; just keep in mind that you will not be able to go back to an orange rom, as there are none available yet. Take also good care with rom having a bootloader greater or equal 1.06; once you flashed your device with one of those you won't be able to flash with anything else but an orange ROM !
There are lot of infos about all that issue on this board, a wizely use of the search tool can give you plenty of infos
