Up-To-Date Basic Tutorial somewhere?

[Mavor]

Hello, I have looked at the examples and tutorials but they are out of date, using SDK 3. Are there any basic tutorials on how to create a server object and use it in iphone SDK 4 out there?

I just want to bring my object into a cocos2d project and then send messages back and forth between server and client... the examples are confusing as heck and not usable.

Thanks!
