hello
as far as i understand there will be not support
i had to ask 3 time´s until nokia germany told me that there will be no rsap support for the n900 and that are no future plans for that

they told me that the n97 has a touchscreen and works with rsap


there are not very costumer oriented

htc and sony phone´s are not working with rsap try the htc touch diamond no way it is not working stable with rsap
only the nokiaphone´s like n97 and e71 are ok
hope the not very helpfull nokia hotline in germany is wrong and the n900 will get rsap it soon
still optimistic
