i don't know.
as far as i understand the devel repository is only meant for people which are experienced because the programs there could cause data loss and system instability.
the program versions in testing should be more stable and less dangerous to use. (but the latest releases are in devel-rep)

this said just look for it in testing first and in devel only if you know what you're doing. (but i have to say that the latest bluemaemo seems to be very stable and well-coded ^^)
