Yeap, it has been merged now. Next version by Konsta will probably include that..
In the Mms application definitions, by default you will have "Mms Auto-retrieval" enabled. It allows to receive and send mms automatically without turning on the data connection. Hopefully, it will be perfect for those who do not have data plans, which is my case.. Just be careful so that "automatic retrieval on roaming" is not selected (by default it is not), or you may have costs while receiving mms in foreign countries..
