Yes. The problem is that it never wants to disconnect a connection. So I will leave my house and it will still show that I am connected to my home wifi even if I am miles from my home. However, as soon as a program needs the internet (facebook/twitter/RSS feeds) it will find my 3G no problem without me manually changing anything. This used to be done autmatically.
And, like you, when I enter my house it will stay on 3G instead of connectiing to my wifi, even though it is an automatic connection...
