A 3.50 PS3 cannot be jail broken. You can however transfer a patch from a 3.41 PS3 to a 3.50 and be able to host lobbies on the 3.50. Tutorials for this have been posted in the Exploits & Hacks section. If you have a PS3 that can be jail broken you only need 1 PS3. This should answer your question. Closed.
