Needrom.com is only a database of what's available, with user submitted content. So it's probably up to you to do your own research and check if whatever you find is safe and suitable for your particular phone. XDA Devs is always a good place to look for information like this. FWIW I've never heard of Digital2, so I assume it's a Chinese device and not really mainstream, unlike say Samsung, HTC or Sony, which can make information about ROMs much more difficult to find. AF doesn't have any information for this phone AFAICT.
