Each Galaxy Tab – the 8.9 and the original 10.1 – has received two Jelly Bean ROMs: one based on AOSP, and the other being CyanogenMod 10. The former is pure Android 4.1 Jelly Bean, the way Google released it while the latter is the same Android 4.1 Jelly Bean but with some modifications on top that enhance Jelly Bean’s own feature set. Every ROM has a slightly different list of features that are working (and non-working). On the Galaxy Tab 8.9, the AOSP ROM is more stable whereas CyanogenMod 10 is more stable on the Galaxy Tab 10.1. Keep in mind that these ROMs haven’t received a good amount of development time, so they are nowhere near up to the mark of what the final official Jelly Bean will be like for the tablets (whenever Samsung decides to push the update, that is).
