I am sorry about the miscommunication, but the Slingbox 350 is supported as along as it is still under warranty. I f you have already returned the Slingbox, you can purchase the Slingbox M1 it is available in your location. Below are some useful links;

i have in the past had a Solo but upgraded to a 350 model.
Unfortunately it is not supported anymore and i returned to supplier for a refund.
I wish to purchase a new model but am concerned about support from Slingbox, any suggestion on which mode,l and who to buy from.
Help would be much appreciated, as i think the idea of Slingbox is great.
