I just looked at the
onyx download page and indeed the newer models are updated to 3.1, while the older are still at 3.0. E.g. Note 3 and Note Air are updated to 3.1, while Note 2 and the Note's are still at 3.0.
Does anyone know whether the older models will be updated, too? Does anyone remember what the lag was for the release of the firmware for the older models when the firmware went to 3.0?
