I have access to a WiFi-network with SSID broadcast disabled and protected using WEP. It works great to connect to the WLAN-network manually using the iPhone, but I have to do it manually every time. The iPhone doesn't remember the network and password, why is that? I'm using iPhone OS 3.0.1 on my 3GS.

Try Resetting all Network Settings, it usually works. Alternatively, try using a $ before your password, i.e., enter $password.
It is not related to the iPhone only. It is not implemented by Apple in the Mac OS X as well. See: Automatically Connecting to Hidden SSID WiFi Network Not that it helps you, but at least you can see you are not the only one :)
